The ICS84330-01 is a general purpose, single out-
put high frequency synthesizer and a member of
the HiPerClockSTM family of High Performance
Clock Solutions from ICS. The VCO operates at a
frequency range of 200MHz to 700MHz. The VCO
and output frequency can be programmed using the serial or
parallel interfaces to the configuration logic. The output can be
configured to divide the VCO frequency by 1, 2, 4, and 8. Out-
put frequency steps from 250KHz to 2MHz can be achieved
using a 16MHz crystal depending on the output divider setting.

N0 through N1 is passed directly to the M divider and N output
divider. On the LOW-to-HIGH transition of the nP_LOAD input,
the data is latched and the M divider remains loaded until the
next LOW transition on nP_LOAD or until a serial event occurs.
The TEST output is Mode 000 (shift register out) when operat-
ing in the parallel input mode. The relationship between the VCO
frequency, the crystal frequency and the M divider is defined as
follows:
The M value and the required values of M0 through M8 are
shown in Table 3B, Programmable VCO Frequency Function
Table. Valid M values for which the PLL will achieve lock are
defined as 100
M 350. The frequency out is defined as
follows:
Serial operation occurs when nP_LOAD is HIGH and S_LOAD
is LOW. The shift register is loaded by sampling the S_DATA
bits with the rising edge of S_CLOCK. The contents of the shift
register are loaded into the M divider when S_LOAD transitions
from LOW-to-HIGH. The M divide and N output divide values
are latched on the HIGH-to-LOW transition of S_LOAD. If
S_LOAD is held HIGH, data at the S_DATA input is passed di-
rectly to the M divider on each rising edge of S_CLOCK. The
serial mode can be used to program the M and N bits and test
bits T2:T0. The internal registers T2:T0 determine the state of
the TEST output as follows:

NOTE: The functional description that follows describes op-
eration using a 16MHz crystal. Valid PLL loop divider values
for different crystal or input frequencies are defined in the In-
put Frequency Characteristics, Table 6, NOTE 1.
The ICS84330-01 features a fully integrated PLL and there-
fore requires no external components for setting the loop band-
width. A quartz crystal is used as the input to the on-chip
oscillator. The output of the oscillator is divided by 16 prior to
the phase detector. With a 16MHz crystal this provides a 1MHz
reference frequency. The VCO of the PLL operates over a
range of 200MHz to 700MHz. The output of the M divider is
also applied to the phase detector.
The phase detector and the M divider force the VCO output fre-
quency to be 2M times the reference frequency divided by 16
by adjusting the VCO control voltage. Note that for some values
of M (either too high or too low), the PLL will not achieve lock.
The output of the VCO is scaled by a divider prior to being sent
to each of the LVPECL output buffers. The divider provides a
50% output duty cycle.
The programmable features of the ICS84330-01 support two
input modes to program the M divider and N output divider. The
two input operational modes are parallel and serial.
Figure 1
shows the timing diagram for each mode. In parallel mode the
nP_LOAD input is LOW. The data on inputs M0 through M8 and

The clock layout topology shown below is a typical termina-
tion for LVPECL outputs. The two different layouts mentioned
are recommended only as guidelines.
FOUT and nFOUT are low impedance follower outputs that
generate ECL/LVPECL compatible outputs. Therefore, terminat-
ing resistors (DC current path to ground) or current sources
must be used for functionality. These outputs are designed to

transmission lines. Matched impedance techniques
should be used to maximize operating frequency and minimize
signal distortion.
Figures 3A and 3B show two different layouts
which are recommended only as guidelines. Other suitable clock
layouts may exist and it would be recommended that the board
designers simulate to guarantee compatibility across all printed
circuit and clock component process variations.

As in any high speed analog circuitry, the power supply pins
are vulnerable to random noise. The ICS84330-01 provides
separate power supplies to isolate any high switching
noise from the outputs to the internal PLL. V
CC
, V
CCA
and V
CCO
should be individually connected to the power supply
plane through vias, and bypass capacitors should be
used for each pin. To achieve optimum jitter performance,
power supply isolation is required.
Figure 2 illustrates how
a 10
resistor along with a 10F and a .01F bypass
capacitor should be connected to each V
CCA
pin.

The ICS84330-01 has been characterized with 18pF parallel
resonant crystals. The external tuning capacitors C1 and C2
are not required if an 18pF parallel resonant crystal is used. If
there is space available, it is recommended to provide spare
footprints C1 and C2 (size 0603 or 0402) while laying out the
P.C. Board. These footprints provide option of optimizing fre-
quency accuracy if needed.

This section provides information on power dissipation and junction temperature for the ICS84330-01.
Equations and example calculations are also provided.
1. Power Dissipation.
The total power dissipation for the ICS84330-01 is the sum of the core power plus the power dissipated in the load(s).
The following is the power dissipation for V
CC
= 3.3V + 5% = 3.465V, which gives worst case results.
NOTE: Please refer to Section 3 for details on calculating power dissipated in the load.
Power (core)
MAX
= V
CC_MAX
* I
EE_MAX
= 3.465V * 115mA = 398.5mW
Power (outputs)
MAX
= 30mW/Loaded Output pair
If all outputs are loaded, the total power is 1 * 30mW = 30mW
Total Power
_MAX
(3.465V, with all outputs switching) = 398.5mW + 30mW = 428.5mW
2. Junction Temperature.
Junction temperature, Tj, is the temperature at the junction of the bond wire and bond pad and directly affects the reliability of the
device. The maximum recommended junction temperature for HiPerClockS
TM
devices is 125C.
The equation for Tj is as follows: Tj =
JA
* Pd_total + T
A
Tj = Junction Temperature
JA
= Junction-to-Ambient Thermal Resistance
Pd_total = Total Device Power Dissipation (example calculation is in section 1 above)
T
A
= Ambient Temperature
In order to calculate junction temperature, the appropriate junction-to-ambient thermal resistance
JA
must be used. Assuming a
moderate air flow of 200 linear feet per minute and a multi-layer board, the appropriate value is 31.1C/W per Table 8A below.
Therefore, Tj for an ambient temperature of 70C with all outputs switching is:
70C + 0.429W * 31.1C/W = 83.3C. This is well below the limit of 125C.
This calculation is only an example. Tj will obviously vary depending on the number of loaded outputs, supply voltage, air flow,
and the type of board (single layer or multi-layer).

3. Calculations and Equations.
The purpose of this section is to derive the power dissipated into the load.
LVPECL output driver circuit and termination are shown in the
Figure 5.
T
o calculate worst case power dissipation into the load, use the following equations which assume a 50
load, and a termination
voltage of V
CCO
- 2V.
For logic high, V
OUT
= V
OH_MAX
= V
CCO_MAX
0.9V
(V
CCO_MAX

) = 0.9V
For logic low, V
OUT
= V
OL_MAX
= V
CCO_MAX
1.7V
(V
CCO_MAX
- V
OL_MAX
) = 1.7V
Pd_H is power dissipation when the output drives high.
Pd_L is the power dissipation when the output drives low.
Pd_H = [(V
OH_MAX
(V
CCO_MAX
- 2V))/R
L
] * (V
CCO_MAX
- V
OH_MAX
) = [(2V - (V
CCO_MAX
- V
OH_MAX
))/R
L
] * (V
CCO_MAX
- V
OH_MAX
) =
[(2V - 0.9V)/50
] * 0.9V = 19.8mW
Pd_L = [(V
OL_MAX
(V
CCO_MAX
- 2V))/R
L
] * (V
CCO_MAX
- V
OL_MAX
) = [(2V - (V
CCO_MAX
- V
OL_MAX
))/R
L
] * (V
CCO_MAX
- V
OL_MAX
) =
[(2V - 1.7V)/50
] * 1.7V = 10.2mW
Total Power Dissipation per output pair = Pd_H + Pd_L = 30mW
