PIN DESCRIPTIONS
Pin # Name Description
1 CLI Cable length indicator. Provides a voltage inversely proportional to the cable length being equalized.
2 V
CC
Positive power supply (+3.3V).
3 V
EE
Negative power supply (ground).
4 SDI Serial data true input.
5 SDI Serial data complement input.
6 V
EE
Negative power supply (ground).
7 AEC+ AEC loop filter external capacitor (1µF) positive connection.
8 AEC- AEC loop filter external capacitor (1µF) negative connection.
9 BYPASS Bypasses equalization and DC restoration when high. No equalization occurs in this mode.
10 MUTE
REF
Mute reference. Determines the maximum cable to be equalized before muting. May be unconnected
for maximum equalization.
11 V
EE
Negative power supply (ground).
12 SDO Serial data complement output.
13 SDO Serial data true output.
14 V
EE
Negative power supply (ground).
15 V
CC
Positive power supply (+3.3V).
16 CD/MUTE Bi-directional carrier detect and output mute. CD/MUTE is high when no signal is present. If
unconnected, MUTE is controlled automatically by carrier detect. To force MUTE on, tie to V
CC
. To
disable MUTE, tie to GND. CD/MUTE has no function in BYPASS mode.
