NAME
FUNCTION
1, 2
IDC-, IDC+
I-Channel Baseband DC Offset Correction. Connect a 0.1μF ceramic chip capacitor from IDC-
to IDC+.
3
VCCRF1
DC Power Supply for LNA and First-Stage RF VGA. Connect to a 5V ±5% low-noise supply.
Bypass with a 1nF capacitor directly to GND. Do not share vias.
4
RFIN-
75
RF-Inverting Input. Working in conjunction with RFIN+ for differential input. Terminate with
22pF capacitor in series with a 75
resistor to GND for single-ended input.
5
RFIN+
75
RF Noninverting Input. Working in conjunction with RFIN- for differential input. Connect to
source through a 22pF series capacitor.
6, 9, 11, 25,
31
N.C.
No Connection. Pin should be connected directly to GND.
7
GC1
Gain Control Input for RF Front End. High-impedance analog input with an operating range of
0.75V to 2.6V. VGC1 = 0.75V corresponds to maximum gain.
8, 28
VREG1, VREG2
2.85V Linear Regulator. Used for terminating open-drain interfaces from demodulator. Each
regulator can source 3mA.
10
PAD
Ground. Direct connection to exposed pad. Can be used to check exposed pad continuity to
ground.
12
VCCLO
DC Power Supply for LO Circuits. Connect to a 5V ±5% low-noise supply. Bypass with a 1nF
capacitor directly to GND. Do not share vias.
13
VCCVCO
DC Power Supply for VCO Circuits. Connect to a 5V ±5% low-noise supply. See the
Applications Information
section for more details.
14
LOFLT
LO Internal Regulator Bypass. Bypass with a 0.22μF ceramic chip capacitor to GND.
