Description
Most negative power supply for analog circuitry.
Connect to GND.
Serial digital differential input.
External AGC capacitor.
Connect pin 5 and pin 6 together as shown in the Typical Application
Circuit on page 13.
Forces the Equalizing and DC RESTORE stages into bypass mode when
HIGH. No equalization occurs in this mode.
Maximum cable length adjust.
Adjusts the approximate maximum amount of cable to be equalized
(from 0m to the maximum cable length). The output is muted (latched to
the last state) when the maximum cable length is achieved.
NOTE: MCLADJ is only recommended for data rates up to 360Mb/s. For
data rates above this, MCLADJ should be left floating.
