Functional Description
The CYV15G0102EQ is a multi-rate adaptive equalizer
designed to equalize and restore signals received over 75Ω
coaxial cable. The equalizer is designed to meet SMPTE
292M, SMPTE 344M, and SMPTE 259M data rates. The
CYV15G0102EQ is optimized to equalize up to 400m of
Belden 1694A coaxial cable at 270 Mbps and up to 200m of
Belden 1694A coaxial cable at 1.485 Gbps. The
CYV15G0102EQ connects seamlessly to the HOTLink II
family of transceiver devices.
The CYV15G0102EQ 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 HD-SDI and SD-SDI data rates. The
Maximum cable length adjust (MCLADJ) sets the approximate
maximum cable length to be equalized at SD and HD data
rates. The CYV15G0102EQ’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 at HD and SD data rates.
Power consumption is typically 160 mW at 3.3V.
