Description
Most negative power supply connection for the input buffer, core,
and control circuits.
Connect to ground.
Serial digital differential input.
Flat Band Gain Control.
Please refer to the DC Electrical Characteristics table for logic level
threshold and compatibility. This pin is a +2.5V input that is tolerant
to +3.3V levels.
When HIGH, the device compensates for an additional 6dB of loss
across the entire operating band.
This pin has an internal pull-down resistor.
External AGC capacitor connection.
EQ Bypass Control.
Please refer to the DC Electrical Characteristics table for logic level
threshold and compatibility. This pin is a +2.5V input that is tolerant
to +3.3V levels.
Forces the equalizer and DC-restore stages into Bypass mode when
HIGH. No equalization occurs in this mode.
This pin has an internal pull-down resistor.
