NAME
FUNCTION
1
IOUT
Inverting I-Channel Baseband Output
PIN
Pin Desc ription
2
IOUT
Noninverting I-Channel Baseband Output
3
V
CC
Downconverter +5V Supply. Bypass with a 10pF capacitor to GND as close to the IC as possible. Connect
an additional 0.1μF capacitor in parallel with the 10pF capacitor.
4
GND
Ground. Connect to a low-inductance ground plane.
5
V
CC
RFIN
RF +5V Supply. Bypass with a 22pF capacitor to GND as close to the IC as possible.
6
Inverting RF Input. Connect to a 22pF capacitor in series with a 75
resistor to GND.
Noninverting RF Input. Connect via matching network to a 75
cable.
7
RFIN
8, 9
GND
RF Ground. Connect to a low-inductance ground plane.
10
GC
Gain-Control Input. Apply a voltage between 1V and 4V to control the gain of the RF amplifier. Bypass with a
1000pF capacitor to minimize noise on the control line.
11
PS_SEL
Prescaler Modulus Control. Drive PS_SEL <0.5V to operate in divide-by-33 mode. Drive PS_SEL >2.4V to
operate in divide-by-32 mode.
12
V
CC
PSOUT
Prescaler +5V Supply. Bypass with a 1000pF capacitor to GND.
13
Inverting Prescaler Output
14
PSOUT
Noninverting Prescaler Output
15
GND
Prescaler Ground. Connect to a low-inductance ground plane.
16
GND
Local Oscillator Ground. Connect to a low-inductance ground plane.
17, 20
N.C.
No Connection. Do not make any connection to this pin.
18
LO
Inverting LO Input
19
LO
Noninverting LO Input
21
V
CC
GND
Local Oscillator +5V Supply. Bypass with a 22pF capacitor and a 0.1μF capacitor to pin 16.
22
Downconverter Ground. Connect to a low-inductance ground plane.
23
QOUT
Noninverting Q-Channel Baseband Output
24
