Equalizer Operation
The CYV15G0101EQ is a high-speed adaptive cable
equalizer designed to equalize standard definition (SD) and
high definition (HD) serial digital interface (SDI) video data
streams. CYV15G0101EQ equalizer is optimized to equalize
up to 350m of Belden 1694A cable
at 270 Mbps and up to
140m of Belden 1694A cable at 1.485 Gbps. The
CYV15G0101EQ equalizer contains one power supply and
typically consumes 160 mW power at 3.3V. The multi-rate
equalizer is designed to meet the SMPTE 259M, SMPTE
292M, SMPTE 344M and DVB-ASI video standards. The
equalizer meets all pathological requirements for SMPTE
292M as defined by RP198 and for SMPTE 259M as defined
by RP178. The CYV15G0101EQ multi-rate Cable Equalizer is
auto-adaptive from 143 Mbps to 1.485 Gbps.
The CYV15G0101EQ equalizer has variable gain and multiple
equalization stages that reverse the effects of the cable. This
equalization is achieved by separate regulation of the lower
and higher frequency components in the signal to give a clean
eye. The CYV15G0101EQ has DC restoration for compen-
sating the DC content of the SMPTE pathological patterns.

I/O Characteristics Signal Description
Analog Output
Cable Length Indicator:
CLI provides an analog voltage proportional to the cable
length being equalized. CLI works at both SD-SDI and HD-SDI data rates.
Carrier Detect/Mute Indicator:
Output:
When the incoming data stream is present, the CD/MUTE outputs a voltage less than
0.8V.
When the incoming data stream is not present, the CD/MUTE outputs a voltage
greater than 2.9V.
Input:
When the CD/MUTE pin is tied to ground, the equalizer’s differential serial outputs
are not muted and the MCLADJ setting is overwritten.
When the CD/MUTE pin is tied to V
CC
, the equalizer’s differential serial outputs are
muted and the MCLADJ setting is overwritten.
Maximum Cable Length Adjust:
The maximum cable length to be equalized is set
by the voltage applied to the MCLADJ input. When the maximum cable length set by
MCLADJ is reached, the differential output is muted. MCLADJ works at both SD and
HD data rates.
Equalizer Bypass:
When BYPASS is tied to V
CC
, 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 tied to GND, 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:
A capacitor of 1
μ
F should be placed 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 can accept either a single ended or differential
serial video data stream over 75
coaxial cable.
