DCoffsetIb
DC offset compensation pin for I-bar arm.
A low pass capacitor shunt to Pin 25 is required.
DC offset compensation pin for I arm.
A low pass capacitor shunt to Pin 24 is required.
Differential output pins of quadrature
demodulator I output. Adding a lowpass shunt
capacitor between these pins will define the
IF bandwidth.
Supply voltage pin of analog portion of the chip.
Gain control voltage pin of IF amplifier. This voltage
performs reverse control,(i.e., V
