) Loop Filter (Output)
This loop filter output is a reference voltage for the re-
ceive path phase detector. It also is a reference for tim-
ing noise immunity circuits in the collision and receive
enable path. Nominal reference V

TEST
Test Control (Input)
A static input that is connected to V

parameters. When TEST is grounded, RX is enabled
and RCLK is enabled except during clock acquisition,
when RCLK is HIGH.
