Equalizer System Connection Diagram
Functional Description
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
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.
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.
Power consumption is typically 160 mW at 3.3V.
