CYV15G0101EQ Equalizer Operation MCLADJ The CYV15G0101EQ is a high speed adaptive cable equalizer Maximum Cable Length Adjust (MCLADJ) sets the approximate designed to equalize standard definition (SD) and high definition maximum amount of cable to be equalized. When the maximum (HD) serial digital interface (SDI) video data streams. cable length set by MCLADJ is reached, CD is driven high and CYV15G0101EQ equalizer is optimized to equalize up to 350m the outputs are muted. MCLADJ works at SD an
