Description
Most positive power supply connection for the input buffer, core
and control circuits.
Connect to +3.3V DC.
Most negative power supply connection for the input buffer, core
and control circuits
Connect to GND.
Serial digital differential input.
Input Sensitivity Control.
Please refer to the input logic parameter in 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.
