Cable Length Indicator. CLI provides an analog voltage proportional to the equalized
cable length. CLI works at both SD-SDI and HD-SDI data rates.
Carrier Detect or Mute Indicator.
Output:
When the incoming data stream is present and the cable length does not exceed the length
that is set by MCLADJ, the CD/MUTE outputs a voltage less than 0.8V.
When the incoming data stream is not present or the cable length exceeds the length that
is set by MCLADJ, the CD/MUTE outputs a voltage greater than 2.8V.
Input:
When the CD/MUTE pin is set LOW, the equalizer's differential serial outputs are not
muted.
When the CD/MUTE pin is set HIGH, the equalizer's differential serial outputs are muted.
Maximum Cable Length Adjust. The maximum equalized cable length is set by the
voltage applied to the MCLADJ input. When the maximum cable length set by MCLADJ
is reached, CD is driven high and the differential output is muted.
If MCLADJ functionality is not needed, then 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).
In equalizer bypass mode, CD/MUTE is not functional.
Automatic Gain Control. Place a capacitor of 1 μF between the AGC± pins.
Differential Serial Outputs. The equalized serial video data stream is presented at the
SDO/SDO differential serial CML output.
Differential Serial Inputs. SDI/SDI accepts either a single-ended or differential serial
video data stream over 75Ω coaxial cable.
+3.3V Power.
Connect to Ground.
