DESCRIPTION OF PIN FUNCTIONS

VDD

Positive supply connection (5 volts). Both pins to be connected.

To be decoupled with a 100nF capacitor to VSS.

VSS

Negative supply connection; system ground (0 volts). Both pins to be connected.

BG

Bias Generator output. To be decoupled with a 100nF capacitor to VSS.

BI

Bias inputs for internal circuitry, both to be connected to BG.

(or external supply referenced to VSS)

PD

Active low. This feature can be used to reduce power consumption for applications that

have a standby mode.

FI1,Fl2

Filter input, FI1 or FI2 depending on filter configuration.

FO

Filter output for all configurations.

LO

Local Oscillator signal input.

MXI

Mixer signal input.

MXO

Mixer signal output.

C1, RC1

Phase advance network nodes. Values R and C set centre frequency, fo.

R2, RC2

Phase retard network nodes. Values R and C set centre frequency, fo.

GP1,2,3

Loop gain programming nodes.
