Caution Short-circuit the XACOMI and XACOMO pins at a location as close to the pins of the
PD9930 as
possible. Connect a capacitor (chip capacitor or electrolytic capacitor) between this short-circuited
portion and analog ground.
The same applies to the RACOMI and RACOMO pins.
The transmission/reception level is determined by these reference pins. Therefore, make sure that
these pins are not affected by noise or fluctuation of ground potential due to current.

2.1.3 Audio Analog Output
Includes receiver output and accessory output. Sidetone addition is also possible.
(1) Post filter 2 (receiver amplifier 1)
This circuit adjusts the gain of D/A differential output signal (volume control), and then converts it to single output
signal.
(2) Receiver drive amplifier (receiver amplifier 2)
This is differential output amplifier that can directly drive a piezo-electric receiver (when using a dynamic receiver,
an additional external amplifier is necessary). The sidetone is added in this circuit.
(3) Post filter 1 (accessory output amplifier)
This circuit converts D/A differential output signal to single output signal. Connected to the earphone of the head
set (capacitance load), etc.

2.1.4 Audio Digital Accessory Output
(1) Ringer output (RINGER pin)
Outputs rectangular waves of the same signal frequency as tone signal frequency.
The output is controlled by turning off power to the output buffer with a control register.
Figure 2-3 RINGER Output
The RINGER signal tends to bounce when the tone output (RAUXO) signal crosses its zero level, and this
tendency increases as the tone output gain decreases (lower than 0 dB).
When using RINGER pin, tune the tone output gain by TNGCR (Tone gain control register) to 0 dB.
(2) Timer (tone interval) output (TIMER pin)
Outputs rectangular waves of the same pattern as the tone signal interrupt pattern. This is used to make the
LED blink in synchronization with the ringer tone.
Figure 2-4 Digital Accessory Output Waveform
2.1.5 Audio Digital Signal Processor
Send signal digital BPF processing, receive signal digital LPF processing, transmission level (digital gain)
control, and tone generation processing.
(1) Voice send signal digital gain fine adjustment function
Performs gain fine adjustment for voice send signal by digital coefficient multiplication. Together with prefilter
gain adjustment, fine adjustment is possible at a width of 5.8 dB.
(2) Voice receive signal digital gain fine adjustment function
Performs fine adjustment of gain for voice receive signal by digital coefficient multiplication.
(3) Tone generation function
Generates single-tone and dual-tone audible signals. Tone frequency, interrupt pattern, gain, generation/stop
can be controlled by microcontroller command. GSM triple tone can be generated by special command.

2.1.6 Power Up/Down Control
The
PD9930 includes a power down function for reducing power consumption. Power down control is by
the two methods described below.
(1) Input/output amplifier power up/down control
Power up/down for both the input and output amplifiers can be controlled.
When the power down function is used for all input amplifiers, both pre-filter and A/D enter the power down state.
When the power down function is used for the accessory output amplifier and the receiver 1 amplifier, the D/A
also enters power down state.
(2) Stand-by mode
Low power consumption can be realized in the mode in which all chip operation is stopped. The stand-by mode
is set by power down command. Operation restarts by power up command.
The following control registers are used to enable the control described above.

Registers Used

(3) Input/output amplifier control register (AMPCR)
This is a 5-bit register for power up/down control of each input/output amplifier (not including receiver amplifier
2), and for ringer output ON/OFF control.
Remark For information on power up/down control of receiver amplifier 2, refer to 4.1.1 Voice Send Analog Gain/
Receiver Amplifier 2 Control Register (TXGCR).
Figure 2-6 Input/Output Amplifier Control Register
Remarks 1. In the stand-by mode, all amplifiers enter the power down state regardless of input/output control register
settings. However, register contents are held unless reset or written, so when the stand-by mode is
cleared by power up command, the command prior to the stand-by mode is resumed.
2. The microphone and accessory amplifiers cannot enter the power up (D4 = D3 = "1") state at the same
time.

2.1.7 Microcontroller Interface
The
PD9930 can control internal functions by microcontroller command. A clock synchronous serial I/O is
incorporated to receive command.
A clocked serial interface is provided to receive microcontroller commands. A microcontroller connection
example is shown in Figure 2-9. 8-bit length data is received by the serial clock (MCLK), serial input (MDAT),
and strobe input (MSTR) lines
Note
.
The timing chart is shown in Figure 2-10. By reading data to the internal shift register and setting MSTR
to high level at the MCLK rising point, it is latched to the internal control register. Data transfer must be made
with LSB first.
Note When 8 bits or more (9 MCLK clocks or more) data is input, the last 8-bit which is input immediately before
the active edge of MSTR is recognized as a control command.

2.1.8 DSP Interface
A clock synchronous serial I/O is built-in to exchange voice send/receive coding data with an external DSP.
16-bit data is transferred at 8 kHz by the serial clock (SCLK = 256 kHz), serial input (SI), serial output (SO),
and enable output (SEN) lines. The REQB is a terminal for allowing/inhibiting data transmission. There are
two modes for data input and output timing, and either can be selected by the DSPSEL terminal. Select the
mode matching the DSP serial interface input/output timing. Data format is as follows: Both SO output and SI
input are in 2's complement format with MSB first.
Figure 2-11 Data Format in DSP Interface
Remark A full code is output when the SO pin is +3.17 dBm0 (A/D 1.2 V
p-p
).
Remark When a full code is input to the SI pin, the accessory output is 1.2 V

2.1.9 DAI (Digital Audio Interface)
Has a on-chip circuit enabling DAI functions specified in GSM11.10. The receive system has a on-chip LPF
only. If a BPF is necessary, it should be mounted externally. System configuration at the time of DAI test mode
is shown in Figure 2-15. The DAI terminal is connected to the system simulator via the pin 25 DSUB socket.
The test mode can be selected by terminals TC1 or TC2, or by microcontroller command. DAI mode should be
set after completing power-up operation (30.5 ms after executing power-up command).
When changing the modes from DAI to normal, either of the following operations should be executed.
After specifying normal mode, input the DAI reset signal (DRSTB = low).
Input reset signal (RESETB = low).
When specifying by command, test control register mode specification bits (ITC1, ITC2) are used (Refer to
4.4.1 Test Control Register (TSTCR).).
Timing for each mode is shown in Figures 2-16 through 2-20.
For operation at the time of each mode, refer to Figure 4-13 Test Mode Operation.

Acoustic device, A/D, Outputs audio data converted into digital signal from DO pin.
D/A test mode
Also inputs audio data input from DI pin to D/A converter. Inputting/outputting data
is started at rising edge of first FSYNC (8-kHz external clock input) after execution
of mode specification. At this time, clock output to DSP (SCLK) is stopped.
Note In the normal mode, do not set DRSTB to low level (during low period, serial interface with DSP is disabled).
As well, set the output pins of driver IC to high-impedance state, because DRSTB input pin is connected with
a pull-up resistor.
Remark Analog loop back mode and DAI test mode cannot be specified at the same time.
DAI test mode is set with TC1, TC2 (or ITC1, ITC2) and DRSTB pins. DAI test mode is entered at the rising
edge of the DRSTB signal when both TC1 and TC2 pins (or ITC1 and ITC2 pins) are set as shown in Figure
2-14.

4. INTERNAL CONTROL FUNCTIONS
The
PD9930 can control internal functions by commands from a microcontroller. Commands consist of 8-
bit data (D7 to D0) consisting of register address and setting data, and are written in the following internal
registers.
Register name
Control
(1)
Voice send analog gain/receiver amplifier 2 control register (TXGCR)
Voice send/receive gain control
(2)
Voice receive analog gain control register (RXGCR)
(3)

Power up/down control
(10) Power up control command (PUPCMD)
(11) Power down control command (PDWCMD)
(12) Test control register (TSTCR)
Test mode control
Remarks 1. In the case of registers (1), (2), and (9) to (11), written contents are executed instantly.
2. For registers (3) to (8) and (12), since fetch execution is made by the internal clock (125
s interval),
keep 125
s or more interval for write-in to the same register.
If the write-in to the same register is executed continuously, the previous command may be ignored.
3. Even when in the stand-by mode, write-in to each internal register is possible (can be held), but the
command written in the register is executed only after clearing the stand-by mode.
4.1 SEND/RECEIVE GAIN CONTROL

4.3 TONE CONTROL
An outline diagram of the tone generator is shown in Figure 4-7. Tone generation is by the tone 1 oscillation
circuit and the tone 2 oscillation circuit.
The tone 1 oscillation circuit generates high group frequency for DTMF and four types of single tones (tone
1 frequency).
The tone 2 oscillation circuit generates low group frequency (tone 2 frequency) for DTMF. Dual tone is output
by adding tone 1 frequency.
In addition to registered tones, other frequencies can be registered. Also, GSM triple tone can be generated
by special command. Examples of tone generation are shown in Figure 4-8.
Tone control items are shown below.

This is a 5-bit register for specifying tone 1 (high group frequency for DTMF and four types of single tones)
and tone 2 (low group frequency for DTMF) frequency combinations.
Figure 4-9 Tone Frequency Selection Register
Write operation in this register is instantaneously executed and retained when a command is received, but
change of tone generation or generating tone is executed only when "1" is written for START/STOP control bit
of the tone control register (refer to Figure 4-11 Tone Control Register).
When a user registration tone is selected, the tone specified by the expanded tone register (refer to Figure
4-10 Expanded Tone Frequency Registration Procedure) is generated.
Caution Do not input a command that sets a tone oscillation frequency after inputting a tone oscillation
command (writing "1" to the START/STOP control bit of the tone control register).

4.3.2 Expanded Tone Registers (EXPR1, EXPR2)
(1) Expanded Tone Frequency Registration Procedure
The
PD9930 can register desired tone frequencies (expanded tone frequencies) in 0.3 to 3.4 kHz range.
Expanded tone register 1 (EXPR1) is for registering expanded tone 1 frequency (high group frequency for DTMF
and single tone). Expanded tone register 2 (EXPR2) is for registering expanded tone 2 frequency (low frequency
for DTMF). The frequency must be specified by 10-bit coefficient (2's complement).
Registration of single tone is done with EXPR1 (single-tone generation is impossible by EXPR2) (refer to Figure
4-10 (a)).
When registering dual tone, set high group in EXPR1 and low group in EXPR2.
Write operation in this register can be executed by continuously writing the expanded tone registration command
and expanded tone data command (refer to Figure 4-10).
Once registered, the frequency is valid until reset or updated.

(2) Expanded Tone Data Determination Method
The coefficient E of the tone frequency fe (0.3 to 3.4 kHz) to be generated is determined by the following formula.
E = COS (2
fe/fs) fs = 8 kHz
Coefficient E: Sign bit 1 bit + 9 bits below the decimal point (Coefficient: 2's complement)
Example When specifying 400 Hz single tone
COS (2
x 400/8000)
= COS (
x 0.1)
= COS (0.3141592653......)
= 0.951056516......
= (0.11110011X) b (Higher-order 9 bits are determined.)
Next, the least significant bit is determined.
When (0.111100110) b = 0.94921875
2
fe' x fs = COS
1
(0.94921875) = 0.320052983
fe' = 0.320052983 x fs/(2
)
fe' = 407.504115
When (0.111100111) b = 0.951071875
2
fe" x fs = COS
1
(0.951071875) = 0.314109559
fe" = 0.314109559 x fs/(2
)
fe" = 399.524415
Since fe" is nearest to 400 Hz, the coefficient to be registered is (0.111100111) b = (1E7) H.

Figure 4-11 Tone Control Register
Notes 1. 950 Hz tone 333 ms, 1400 Hz tone 333 ms, 1800 Hz tone 333 ms, 1 s no tone repeated.
2. Do not input a command that sets a tone oscillation frequency after inputting a tone oscillation command
(writing "1" to the START/STOP control bit of the tone control register).
Remark When the regeneration pattern is specified as "110", it becomes GSM triple tone command, so tone
generation forcibly enters single tone mode.
Tone generation and change of a tone that is being generated is executed only when "1" is written for START/
STOP control bit (D0 bit) (refer to Figure 4-11 and Table 4-6).

Cautions 1. Connect the AGND1 through AGND4 pins and DGND pin to an analog ground line near
PD9930
pins. Connect the DV
DD
, AV
DD1
, AV
DD2
pins to an analog power supply line near
PD9930 pins.
2. Do not connect output (and bidirectional) pins each other. Do not connect output (or bidirec-
tional) pins directly to the V
DD
, V
CC
, or GND line. However, open drain pin and open collector
pin can be directly connected to V
DD
, V
CC
, or GND line. If timing design is made so that no signal
conflict occurs, three-state pins can also be connected directly to three-state pins of external
circuit.
3. Exposure to Absolute Maximum Ratings for extended periods may affect device reliability;
exceeding the ratings could cause permanent damage. The parameters apply independently.
The device should be operated within the limits specified under DC and AC Characteristics.

Send/receive zero transmission level (0 dBm0 level) is explained below for your reference.
(a) Send zero transmission level
Analog output signal level at which the digital input signal level of the D/A converter becomes 0 dBm0.
(b) Receive zero transmission level
Analog input signal level at which the digital output signal level of the A/D converter becomes 0 dBm0.
(c) Analog signal level (dBm)
The conversion expression of the amplitude voltage of a signal and an analog signal level is as follows:
X = 10 logW
X: analog signal level (dBm)
W: analog signal power (mW)
W = (V
2
/R) x 10
3
V: effective value of analog signal (AC) (Vrms)
R: resistance (
)
With the
PD9930, the signal voltage (effective value) can be calculated if R = 600
and X = 8.4 dBm are
substituted.
W = 0.1445 (mW)
V = 0.294 (Vrms)
To calculate V
0-p
, multiply the signal voltage (effective value) by
2.
V
0-p
= 0.416 (V)
(d) Digital signal level (dBm0)
Signal level where the level of the full swing of the digital output value of the A/D converter and the digital input
value of the D/A converter is considered to be 3.17 dBm0 (the amplitude of the analog signal is 1.2 V
p-p
where
the gain of the microphone input or accessory input is 0 dB).
<Level diagram>

NOTES FOR CMOS DEVICES
1
PRECAUTION AGAINST ESD FOR SEMICONDUCTORS
Note: Strong electric field, when exposed to a MOS device, can cause destruction
of the gate oxide and ultimately degrade the device operation. Steps must
be taken to stop generation of static electricity as much as possible, and
quickly dissipate it once, when it has occurred. Environmental control must
be adequate. When it is dry, humidifier should be used. It is recommended
to avoid using insulators that easily build static electricity. Semiconductor
devices must be stored and transported in an anti-static container, static
shielding bag or conductive material. All test and measurement tools
including work bench and floor should be grounded. The operator should
be grounded using wrist strap. Semiconductor devices must not be touched
with bare hands. Similar precautions need to be taken for PW boards with
semiconductor devices on it.
2
HANDLING OF UNUSED INPUT PINS FOR CMOS
Note: No connection for CMOS device inputs can be cause of malfunction. If no
connection is provided to the input pins, it is possible that an internal input
level may be generated due to noise, etc., hence causing malfunction. CMOS
device behave differently than Bipolar or NMOS devices. Input levels of
CMOS devices must be fixed high or low by using a pull-up or pull-down
circuitry. Each unused pin should be connected to V
DD
or GND with a
resistor, if it is considered to have a possibility of being an output pin. All
handling related to the unused pins must be judged device by device and
related specifications governing the devices.
3
STATUS BEFORE INITIALIZATION OF MOS DEVICES
Note: Power-on does not necessarily define initial status of MOS device. Produc-
tion process of MOS does not define the initial operation status of the device.
Immediately after the power source is turned ON, the devices with reset
function have not yet been initialized. Hence, power-on does not guarantee
out-pin levels, I/O settings or contents of registers. Device is not initialized
until the reset signal is received. Reset operation must be executed imme-
diately after power-on for devices having reset function.

this document.
NEC Corporation does not assume any liability for infringement of patents, copyrights or other intellectual property
rights of third parties by or arising from use of a device described herein or any other liability arising from use
of such device. No license, either express, implied or otherwise, is granted under any patents, copyrights or other
intellectual property rights of NEC Corporation or others.
While NEC Corporation has been making continuous effort to enhance the reliability of its semiconductor devices,
the possibility of defects cannot be eliminated entirely. To minimize risks of damage or injury to persons or
property arising from a defect in an NEC semiconductor device, customers must incorporate sufficient safety
measures in its design, such as redundancy, fire-containment, and anti-failure features.
NEC devices are classified into the following three quality grades:
"Standard", "Special", and "Specific". The Specific quality grade applies only to devices developed based on a
customer designated "quality assurance program" for a specific application. The recommended applications of
a device depend on its quality grade, as indicated below. Customers must check the quality grade of each device
before using it in a particular application.
Standard: Computers, office equipment, communications equipment, test and measurement equipment,
audio and visual equipment, home electronic appliances, machine tools, personal electronic
equipment and industrial robots
Special:
Transportation equipment (automobiles, trains, ships, etc.), traffic control systems, anti-disaster
systems, anti-crime systems, safety equipment and medical equipment (not specifically designed
for life support)
Specific:
Aircrafts, aerospace equipment, submersible repeaters, nuclear reactor control systems, life
support systems or medical equipment for life support, etc.
The quality grade of NEC devices is "Standard" unless otherwise specified in NEC's Data Sheets or Data Books.
If customers intend to use NEC devices for applications other than those specified for Standard quality grade,
they should contact an NEC sales representative in advance.
Anti-radioactive design is not implemented in this product.
