CLI
O
Cable Length Indication
. Provides a voltage output representing the amount of cable being
equalized. See figures 19 and 20. The CLI voltage is an approximation of the cable length
being equalized. It is intended as a guide for troubleshooting the initial design and not as an
accurate indication of cable length.

MCLADJ
I
Adjusts the 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
reached. To achieve maximum cable length, this pin should be left open. See figures 10 - 12.

CD/Mute
I/O
Carrier Detect/Mute Indicator/Control
. When the CD/Mute output is low, the carrier is present
and the data output is active. When the CD/Mute output is high, the carrier is not present and
the data output is muted (latched to the last state). This indicates that the maximum cable
length as set by MCLADJ has been reached.
The above default CD/Mute function can be overwritten as follows: if the CD/Mute pin is tied
to ground the data output will not mute and the MCLADJ setting is overwritten. If the mute pin
is tied high, the data output will always mute and the MCLADJ setting is overwritten.
