Mute. When the MUTE pin is set LOW, the equalizer’s differential serial outputs are not
muted.
When the MUTE pin is set HIGH, the equalizer’s differential serial outputs are muted.
BYPASS setting is ignored when MUTE is HIGH.
Connecting CD to the MUTE pin enables automatic muting of the equalizer when the
signal is lost.
Do not leave an unused MUTE pin floating. Always drive it to a known state.
Carrier Detect. When the incoming data stream is present and maximum cable length
does not exceed that set by MCLADJ, CD outputs a voltage less than 0.8V.
When the incoming data stream is not present or maximum cable length exceeds that set
by MCLADJ, CD outputs a voltage greater than 2.8V.
Connecting CD to the MUTE pin enables automatic muting of the equalizer upon loss of
signal.
Maximum Cable Length Adjust. The maximum cable length to equalize is set by the
voltage applied to the MCLADJ input. When the maximum cable length set by MCLADJ
is reached, the CD indicator deasserts.
If MCLADJ functionality is not needed, this pin should be left floating or tied to ground to
allow maximum equalized cable length.
MCLADJ works at both SD and HD data rates.
Equalizer Bypass. When BYPASS is set HIGH, the signal presented at the equalizer’s
differential serial inputs (SDI, SDI) is routed to the equalizer’s differential serial outputs
(SDO, SDO) without equalizing.
When BYPASS is set LOW, the incoming video data stream is equalized and presented
at the equalizer‘s serial differential outputs (SDO, SDO).
When the MUTE pin is set HIGH, the BYPASS setting is ignored and the serial outputs
are muted.
Automatic Gain Control. Place a capacitor of 1 μF between the AGC and AGC pins.
Differential Serial Outputs. The equalized serial video data stream is presented at the
SDO/SDO differential serial CML output.
