Name
IO Characteristics Signal Description
Control Signals
CLI
Analog Output
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.
CD/MUTE
LVTTL IO
Carrier Detect or Mute Indicator.
Output:
When the incoming data stream is present and the cable length does not exceed that 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 that 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.
MCLADJ
Analog Input
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, 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.
BYPASS
LVTTL Input
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 performing equalization.
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.
AGC±
Analog
Automatic Gain Control. Place a capacitor of 1
μF between the AGC± pins.
SDO, SDO
Differential
Output
Differential Serial Outputs. The equalized serial video data stream is presented at the
SDO/SDO differential serial CML output.
SDI, SDI
Differential
Input
Differential Serial Inputs. SDI/SDI accepts either a single-ended or differential serial video
data stream over 75
Ω coaxial cable.
