Functional Description
The CYV270M0101EQ is an adaptive video cable equalizer
designed to equalize and restore signals received over 75
Ω
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.
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.
