CYV15G0100EQ Equalizer Operation MCLADJ The CYV15G0100EQ 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. MCLADJ works at (HD) serial digital interface (SDI) video data streams. The SD and HD data rates. CYV15G0100EQ equalizer is optimized to equalize up to 175m If the MCLADJ voltage is greater than the CLI output voltage, the of Canare L
