The CYV270M0101EQ is an adaptive video cable equalizer
designed to equalize and restore signals received over 75Ω
coaxial cable. The equalizer meets SMPTE 259M data rates and
is optimized for performance at 270 Mbps. The
CYV270M0101EQ is optimized to equalize up to 350m of
Canare L-5CFB and Belden 1694A coaxial cable at 270 Mbps.
The CYV270M0101EQ connects seamlessly to the HOTLink II
family of transceivers and HOTLink receivers.

receiver
■
Equalizes up to 350m of Canare L-5CFB and Belden 1694A
coaxial cable at 270 Mbps
■

Pin compatible to existing equalizer devices
The CYV270M0101EQ has DC restoration for compensation of
the DC content of the SMPTE pathological patterns. A cable
length indicator (CLI) provides an indication of the cable length
equalized at SD-SDI data rates. The maximum cable length
adjust (MCLADJ) sets the approximate maximum cable length to
equalize. The CYV270M0101EQ differential serial outputs
(SDO, SDO) mute when the approximate cable length set by
MCLADJ is reached. CD/MUTE is a bidirectional pin that
provides an indication of the signal present at the equalizer
inputs. It also controls muting the outputs of the equalizer.
Power consumption is typically 160 mW at 3.3V.

CLI
Analog Output
Cable Length Indicator. CLI provides an analog voltage proportional to the equalized
cable length.
CD/MUTE
LVTTL IO
Carrier Detect/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.
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 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.

CYV270M0101EQ
Equalizer Operation
MCLADJ
The CYV270M0101EQ is an adaptive video cable equalizer
designed to equalize standard definition (SD) serial digital
interface (SDI) video data streams. The CYV270M0101EQ
equalizer is optimized to equalize up to 350m of Canare L-5CFB
and Belden 1694A cable at 270 Mbps. The device contains one
power supply and typically consumes 160 mW power at 3.3V.
The adaptive equalizer meets the SMPTE 259M and DVB-ASI
video standards. It meets all pathological requirements for
SMPTE 259M as defined by RP178. The CYV270M0101EQ
Video Cable Equalizer is auto adaptive from 143 Mbps to 360
Mbps.
Maximum Cable Length Adjust (MCLADJ) sets the approximate
maximum amount of cable to be equalized.
The CYV270M0101EQ 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 output
eye diagram. The CYV270M0101EQ has DC restoration to
compensate the DC content of the SMPTE pathological patterns.
SDI, SDI
The CYV270M0101EQ accepts single-ended or differential
serial video data streams over 75Ω coaxial cable. It is recommended to AC couple the SDI and SDI inputs as they are internally biased to 1.2V.
SDO, SDO
The CYV270M0101EQ has differential serial output interface
drivers that use current mode logic [CML] drivers to provide
source matching for the transmission line. These outputs are
either AC coupled or DC coupled to the HOTLink II SerDes
device.
CLI
Cable Length Indicator (CLI) is an analog output that gives an
output voltage proportional to the equalized cable length. CLI
gives an approximation of the length of cable at the differential
serial inputs (SDI, SDI). CLI works at standard definition (SD)
data rates. The graph in Figure 3 on page 7 illustrates the CLI
output voltage at various Belden 1694A cable lengths. With an
increase in cable length, CLI output voltage decreases.
If the MCLADJ voltage is greater than the CLI output voltage, CD
is driven high and the equalizer serial differential outputs (SDO,
SDO) are muted. If the MCLADJ voltage is less than CLI voltage,
then the equalizer’s differential serial outputs (SDO, SDO) are
not muted and the incoming data stream is equalized. The graph
in Figure 2 on page 7 illustrates the voltage required at MCLADJ
input to equalize various Belden 1694A cable lengths for SD data
rates. If MCLADJ functionality is not required, this pin should be
left floating or tied to ground to allow maximum equalized cable
length.
CD/MUTE
Carrier Detect/MUTE (CD/MUTE) is a bidirectional pin that
provides an indication of the signal present at the equalizer’s
input, or it controls the muting of the equalizer’s output.
If CD/MUTE is used as an output and the incoming data stream
is not present or the cable length exceeds that set by MCLADJ,
the voltage at the CD/MUTE output is greater than 2.8V. If
CD/MUTE is used as an output, the incoming data stream is
present and the cable length does not exceed that set by
MCLADJ, then the voltage at the CD/MUTE output is less than
0.8V.
If CD/MUTE is used as an input, and set LOW, the equalizer
serial outputs are not muted. If the CD/MUTE is used as an input
and is set HIGH, then the equalizer serial outputs are muted.
When an invalid signal or a signal transmitted with a launch
amplitude of less than 500 mV at SD data rates is received, the
equalizer’s serial outputs are muted and the MCLADJ setting is
overwritten.
BYPASS
The CYV270M0101EQ has a bypass mode that allows the user
to bypass the equalizer’s equalization and DC restoration
functions. When the Bypass mode is tied to VCC, 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 differential serial
outputs (SDO, SDO).
In equalizer bypass mode, CD/MUTE is not functional.
AGC
Place a capacitor of 1 μF between the AGC± pins of the
CYV270M0101EQ equalizer.
