Pin Descriptions
PIN NUMBER
NAME
DESCRIPTION
1
BYP+
DC feedback pin for the AGC amplifier. Requires good RF decoupling to a solid ground.
2
IF_CDMA+
Non-inverting analog input of the AGC amplifier, CDMA channel.Requires a DC blocking
capacitor. A parallel differential DC coupled resistor setting the input impedance with its
complementary input is possible.
3
IF_CDMA-
Inverting analog input of the AGC amplifier, CDMA channel. Requires a DC blocking ca-
pacitor. A parallel differential DC coupled resistor setting the input impedance with its com-
plementary input is possible. AC couple to ground if the port is to be used single ended.
4
GND
Ground. Connect to a solid ground plane.
5
IF_FM+
Non-inverting analog input of the AGC amplifier, FM channel. Requires a DC blocking ca-
pacitor. A parallel differential DC coupled resistor setting the input impedance with its com-
plementary input is possible.
6
IF_FM-
Inverting analog input of the AGC amplifier, FM channel. Requires a DC blocking capacitor.
A parallel differential DC coupled resistor setting the input impedance with its complemen-
tary input is possible. AC couple to ground if the port is to be used single ended.
7
BYP -
DC feedback pin for the AGC amplifier. Require good RF decoupling to a solid ground.
8
AGC_CTRL
AGC current control input. Requires a 15K 1% series resistor.
9
SEL
Selects the CDMA or FM AGC Amplifier differential input. HIGH selects the CDMA input;
LOW selects the FM input.
10
RX_PE
Power enable control input. HIGH for normal operation. LOW for power down.
11
GND
Ground. Connect to a solid ground plane.
12
GND_LO
LO_IN input ground return. Ground to Local Oscillator ground plane or transmission line.
13
V+_LO
LO divider network Power Supply. Use high quality RF decoupling capacitors at the pin.
14
LO_IN
Current input from the Local Oscillator. Use a 50
power to current converter. See appli-
cations diagram. Requires a DC blocking capacitor.
15
GND_AMP
IF output amplifiers ground return.
16
IOUT-
Negative I channel baseband output. Requires a DC blocking capacitor.
17
IOUT+
Positive I channel baseband output. Requires a DC blocking capacitor.
18
GND
Ground. Connect to a solid ground plane.
19
QOUT-
Negative Q channel baseband output. Requires a DC blocking capacitor.
20
QOUT+
Positive Q channel baseband output. Requires a DC blocking capacitor.
21
V+_AMP
IF output amplifier Power Supply. Use high quality RF decoupling capacitors at the pin.
22
DEMOD+
Positive input of the quadrature demodulator. Requires a DC blocking capacitor.
23
DEMOD -
Negative input of the quadrature demodulator. Requires a DC blocking capacitor.
24
GND_AGC
AGC amplifier main ground return.
25
GND
Ground. Connect to a solid ground plane.
26
IF_OUT-
Negative output from the AGC amplifier. Requires a DC blocking capacitor.
27
IF_OUT+
Positive output from the AGC amplifier. Requires a DC blocking capacitor.
28
V+_AGC
AGC amplifier Power Supply. Use high quality RF decoupling capacitors at the pin.
