CYV270M0101EQ  
Adaptive Video Cable Equalizer (SOIC)  
Features  
Functional Description  
• Adaptive Cable Equalization  
The CYV270M0101EQ 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  
• SMPTE 259M Compliant  
• Supports DVB-ASI at 270 Mbps  
Mbps. The CYV270M0101EQ is optimized to equalize up to  
350m of Belden 1694A coaxial cable at 270 Mbps. The  
CYV270M0101EQ connects seamlessly to the HOTLink II  
family of transceiver devices and HOTLink(R) receiver  
devices.  
• Multi-standard operation from 143 Mbps to 360 Mbps  
• Cable Length Indicator for SD-SDI data rates  
• Maximum Cable Length Adjustment for SD-SDI data rates  
• Carrier detect and Mute functionality for SD-SDI data rates  
• Equalizer Bypass Mode  
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  
being equalized at SD-SDI data rates. The Maximum cable  
length adjust (MCLADJ) sets the approximate maximum cable  
length to be equalized. The CYV270M0101EQ’s 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 being present at  
the equalizer inputs. It also controls muting the outputs of the  
equalizer.  
• Seamless connection with HOTLink II™ Family, HOTLink  
(R)™ Receiver  
• Equalizes up to 350m of Belden 1694A coaxial cable at 270  
Mbps  
• Low Power 160 mW @ 3.3V  
• Single 3.3V supply  
• 16-pin SOIC  
• 0.18-µm CMOS technology  
• Pb-free and RoHS compliant  
• Pin-compatible to existing equalizer devices  
Power consumption is typically 160 mW at 3.3V.

0.8V.  
When the incoming data stream is not present, the CD/MUTE outputs a voltage  
greater than 2.9V.

When the CD/MUTE pin is tied to ground, the equalizer’s differential serial outputs

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.  
Equalizer Bypass: When BYPASS is tied to V , the signal presented at the

serial outputs (SDO, SDO) without performing equalization.  
When BYPASS is tied to GND, the incoming video data stream is equalized and

Equalizer Operation  
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 Belden 1694A  
cable at 270 Mbps. The CYV270M0101EQ equalizer contains  
one power supply and typically consumes 160 mW power at  
3.3V. The adaptive equalizer is designed to meet the SMPTE  
259M and DVB-ASI video standards. The equalizer 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.  
cable. This equalization is achieved by separate regulation of  
the lower and higher frequency components in the signal to  
give a clean eye. The CYV270M0101EQ has DC restoration  
for compensating 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 recom-  
mended to AC-couple the SDI, SDI inputs as they are inter-  
nally biased to 1.2V.

equalizer’s input, or it controls the muting of the equalizer’s  
output.  
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 can  
be either AC coupled or DC coupled to the HOTLink II SerDes  
device.  
If CD/MUTE is used as an output, and the incoming data  
stream is not present, the voltage at the CD/MUTE output will  
be greater than 2.9V. If CD/MUTE is used as an output, and  
the incoming data stream is present, then the voltage at the  
CD/MUTE output will be less than 0.8V.  
If CD/MUTE is used as an input, and tied to ground, the  
equalizer serial outputs are not muted and the MCLADJ  
setting is overwritten. If the CD/MUTE is used as an input and  
CLI  
Cable Length Indicator (CLI) is an analog output that gives an  
output voltage proportional to the cable length being  
equalized. 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 2 illus-  
trates the CLI output voltage at various Belden 1694A cable  
lengths. With an increase in cable length, CLI output voltage  
decreases.

When an invalid signal or a signal transmitted with a launch

presented at the equalizer’s differential serial inputs (SDI, SDI)  
is routed to the equalizer’s differential serial outputs (SDO,  
SDO) without performing equalization.  
If the MCLADJ voltage is greater than the CLI output voltage,  
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 1 illustrates the voltage needed at MCLADJ input, to  
equalize various Belden 1694A cable lengths for SD data  
rates. The MCLADJ pin can be left unconnected in applica-  
tions that do not require muting of the outputs.  
When BYPASS is tied to GND, the incoming video data stream  
is equalized and presented at the equalizer‘s differential serial  
outputs (SDO, SDO).
