Texas Instruments LMH12x9 12G SDI Cable Equalizers
Texas Instruments LMH12x9 12G SDI Cable Equalizers are long-reach adaptive cable equalizers with an integrated reclocker, dual outputs, and 75Ω loop-through output. The device is designed to equalize data transmitted over 75Ω coaxial cable and operates across SMPTE data rates ranging from 125Mbps to 11.88Gbps. The adaptive equalizer at the SDI input enables automatic loss compensation for up to 100m Belden 1694A cable reach in 4K/8K video applications where 12G-SDI (11.88Gbps) is used. The integrated reclocker attenuates high-frequency jitter and fully regenerates the data using a clean, low-jitter clock. The loop filter of the reclocker is adjustable with an optional external capacitor to reduce the CDR loop bandwidth.
