The RF2919 is a monolithic integrated circuit intended for
use as a low cost ASK/OOK receiver. The device is pro-
vided in 32-lead plastic packaging and is designed to pro-
vide a fully functional AM receiver. The chip is intended
for applications in the North American 915MHz ISM band
and European 433MHz and 868MHz ISM bands. The
integrated VCO, +64 prescaler, and reference oscillator
require only the addition of an external crystal to provide
a complete phase-locked oscillator for single channel
applications. A data comparator is included to provide
logic level outputs.

Pin
Function
Description
Interface Schematic
1
VCC1
This pin is used to supply DC bias to the receiver RF circuits. An RF
bypass capacitor should be connected directly to this pin and returned
to ground. A 100pF capacitor is recommended for 915MHz applica-
tions. A 220pF capacitor is recommended for 433MHz applications.
2
RX IN
RF input pin for the receiver electronics. RX IN input impedance is a
low impedance when enabled. RX IN is a high impedance when the
receiver is disabled.
3
GND1
Ground connection for RF receiver functions. Keep traces physically
short and connect immediately to ground plane for best performance.
4
LNA OUT
Output pin for the receiver RF low noise amplifier. This pin is an open
collector output and requires an external pull up coil to provide bias and
tune the LNA output.
5
GND2
GND2 is connection for the 40 dB IF limiting amplifier. Keep traces
physically short and connect immediately to ground plane for best per-
formance.
6
MIX IN
RF input to the RF Mixer. An LC matching network between LNA OUT
and MIX IN can be used to connect the LNA output to the RF mixer
input in applications where an image filter is not needed or desired.
7
GND3
GND3 is the ground connection for the receiver RF mixer.
8
MIX OUT
IF output from the RF mixer. Interfaces directly to 10.7MHz ceramic IF
filters as shown in the application schematic. A pull-up inductor and
series matching capacitor should be used to present a 330
termina-
tion impedance to the ceramic filter. Alternately, an IF tank can be used
to tailor the IF frequency and bandwidth to meet the needs of a given
application. In addition to the matching components, a 15pF capacitor
should be placed from this pin to ground.
9
IF1 IN-
Balanced IF input to the 40dB limiting amplifier strip. A DC blocking
capacitor is required on this input, 10nF is recommended.
10
IF1 IN+
Functionally the same as pin 9 except non-inverting node amplifier
input. In single-ended applications, this input should be bypassed
directly to ground through a 10 nF capacitor.
See pin 9.
11
IF1 BP+
DC feedback node for the 40dB limiting amplifier strip. A 10nF bypass
capacitor from this pin to ground is recommended.
See pin 9.
12
IF1 BP-
See pin 11.
See pin 9.
13
IF1 OUT
IF output from the 40dB limiting amplifier. The IF1 OUT output presents
a nominal 330
output resistance and interfaces directly to 10.7MHz
ceramic filters.
14
VREF IF
DC voltage reference for the IF limiting amplifiers (typically 1.1V). A
10nF capacitor from this pin to ground is recommended.
15
GND5
Ground connection for 60dB IF limiting amplifier. Keep traces physically
short and connect immediately to ground plane for best performance.

Inverting input to the 60dB limiting amplifier strip. A 10 nF DC blocking
capacitor is required on this input. The IF2 IN input presents a nominal
330
input resistance and interfaces directly to 10.7MHz ceramic fil-
ters.

VCC3
This pin is used is supply DC bias to the 60dB IF limiting amplifier. An
IF bypass capacitor should be connected directly to this pin and
returned to ground. A 10 nF capacitor is recommended for 10.7MHz IF
applications.
20
MUTE
This pin is used to mute the data output (DATA OUT). MUTE>2.0V
turns the DATA OUT signal on. MUTE<1.0V turns the DATA OUT sig-
nal off.
21
RSSI
A DC voltage proportional to the received signal strength is output from
this pin. The output voltage increases with increasing signal strength.
22
DATA IN-
The inverting input of the data comparator. The RSSI is fed to this pin
via a 50k
resistor. This input is available for a data filtering capacitor
that provides noise and 2x IF rejection. The value of the capacitor can
be calculated by C= 1/(2
F*50k
) where F is the desired 3dB band-
width.
23
DATA OUT
The data comparator output which contains the modulating data recov-
ered from the RSSI signal. Hysteresis can be added to the comparator
by placing a very large (<1M
) resistor between pins 23 and 24.The
magnitude of the load impedance is intended to be 1M
or greater.
24
DATA IN+
The non-inverting input of the data comparator. The RSSI is fed to this
pin via a 50k
resistor. This input is available for a large filtering capac-
itor such that the modulation signal can be filtered out leaving a DC ref-
erence signal for the comparator.
See pin 22.
25
RESNTR-
This port is used to supply DC voltage to the VCO as well as to tune the
center frequency of the VCO. Equal value inductors should be con-
nected to this pin and pin 26.
26
RESNTR+
See pin 25.
See pin 25.
27
VCC2
This pin is used is supply DC bias to the VCO, prescaler, and PLL. An
IF bypass capacitor should be connected directly to this pin and
returned to ground. A 10nF capacitor is recommended for 10.7MHz IF
applications.
28

GND4 is the ground shared on chip by the VCO, prescaler, and PLL
electronics.
