Functional Description

The CYV15G0101EQ is a multi rate adaptive equalizer designed to equalize and restore signals received over 75Ω coaxial cable. The equalizer meets SMPTE 292M, SMPTE 344M, and SMPTE 259M data rates. The CYV15G0101EQ is optimized to equalize up to 350m of Belden 1694A coaxial cable at 270 Mbps and typically up to 200m of Belden 1694A coaxial cable at 1.485 Gbps. The CYV15G0101EQ connects seamlessly to the HOTLink II family of transceivers.

The CYV15G0101EQ has DC restoration to compensate for 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 equalize at SD and HD data rates. The CYV15G0101EQ’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 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.
