The CYV270M0104EQ is an adaptive video cable equalizer
designed to equalize and restore signals received over 75Ω
coaxial cable. The equalizer is designed to meet SMPTE 259M
data rates and is optimized for performance at 270 Mbps. The
CYV270M0104EQ is optimized to equalize up to 350m of Belden
1694A and Canare L-5CFB coaxial cable at 270 Mbps. The
CYV270M0104EQ connects seamlessly to the HOTLink II family
of transceiver devices and HOTLink receiver devices.

■
Equalizes up to 350m of Belden 1694A and Canare L-5CFB
coaxial cable at 270 Mbps
■
Low power: 160 mW at 3.3V
■
Single 3.3V supply

■
Uses Cypress CLEANLink™ technology
The CYV270M0104EQ has DC restoration to compensate for
the DC content of the SMPTE pathological patterns. The
maximum cable length adjust (MCLADJ) sets the approximate
maximum cable length to equalize. The CYV270M0104EQ’s
differential serial outputs (SDO, SDO) mute, when the approximate cable length set by MCLADJ is reached and carrier detect
(CD) is tied to MUTE. The MUTE pin controls muting of the
equalizer outputs.
Power consumption is typically 160 mW at 3.3V.

Signal Description
Control Signals
MUTE
LVTTL Input
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. The
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.
CD
LVTTL Output
Carrier Detect. When the incoming data stream is present and maximum cable length set
by MCLADJ is not exceeded, CD outputs a voltage less than 0.8V.
When the incoming data stream is not present or maximum cable length set by MCLADJ
is exceeded, CD outputs a voltage greater than 2.8V.
Connecting CD to the MUTE pin enables automatic muting of the equalizer when the signal
is lost.
MCLADJ
Analog Input
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 required, then 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 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).
When MUTE is set HIGH, the BYPASS setting is ignored and the serial outputs are muted.
AGC, AGC
Analog
Automatic Gain Control. Place a 1 μF capacitor between the AGC and AGC pins.
SDO, SDO

Differential Serial Outputs. The equalized serial video data stream is presented at the

CYV270M0104EQ
Equalizer Operation
MUTE
The CYV270M0104EQ is an adaptive video cable equalizer that
equalizes standard definition (SD) serial digital interface (SDI)
video data streams. The CYV270M0104EQ equalizer is
optimized to equalize up to 350m of Belden 1694A and Canare
L-5CFB 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 CYV270M0104EQ Video Cable
Equalizer is auto adaptive from 143 Mbps to 360 Mbps.
MUTE is an input pin that controls the muting of the equalizer’s
output.
The CYV270M0104EQ equalizer has multiple variable gain
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 CYV270M0104EQ has DC restoration for
compensating the DC content of the SMPTE pathological
patterns.
SDI, SDI
CYV270M0104EQ accepts single-ended or differential serial
video data streams over 75Ω coaxial cable. It is recommended
to AC couple the SDI and SDI inputs because they are internally
biased to 1.2V.
SDO, SDO
The CYV270M0104EQ 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 HOTLink II receivers.
MCLADJ
If MUTE is set LOW, then the equalizer serial outputs are not
muted. If MUTE is set HIGH, then the equalizer serial outputs are
muted. When MUTE is active, the BYPASS setting is also
ignored.
Connecting CD to MUTE enables automatic muting of the
equalizer when the signal is lost.
Do not leave the MUTE pin floating. Always drive it to a known
state.
Carrier Detect (CD)
Carrier Detect is an active LOW output pin that indicates the
presence of a valid incoming data signal. When the incoming
data signal is present and maximum cable length does not
exceed the length that is set by MCLADJ, CD outputs a voltage
less than 0.8V.
When the incoming data stream is not present or maximum cable
length exceeds the length that is set by MCLADJ, CD outputs a
voltage greater than 2.8V.
Connecting CD to MUTE enables automatic muting of the
equalizer when the signal is lost.
BYPASS
The CYV270M0104EQ has a bypass mode that enables the user
to bypass the equalizer’s equalization and DC restoration
functions. 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.
Maximum Cable Length Adjust (MCLADJ) sets the approximate
maximum amount of cable to equalize. When the maximum
cable length set by MCLADJ is reached, the CD pin deasserts.
To enable automatic muting of the device when the signal is lost,
tie CD directly to MUTE.
When BYPASS is set LOW, the incoming video data stream is
equalized and presented at the equalizer‘s differential serial
outputs (SDO, SDO).
The graph in Figure 2 on page 7 illustrates the voltage required
at MCLADJ input to equalize various Belden 1694A cables. The
same graph applies for Canare L-5CFB cables. If MCLADJ
functionality is not required, this pin should be left floating or tied
to ground to allow maximum equalized cable length.
Place a 1 μF capacitor between the AGC and AGC pins of the
CYV270M0104EQ equalizer.
