Welcome Here  Shenzhen Mingjiada Electronics Co., Ltd.

The LMH1239RTVR is a 12G SDI dual cable equalizer with an integrated clock recoverer. The device is designed to equalize data transmitted over 75Ω coaxial cables and can operate in the SMPTE data rate range of 125Mbps to 11.88Gbps.

The adaptive equalizer at the SDI input automatically compensates for signal losses of up to 100m Belden 1694A cables in 4K/8K video applications using 12G-SDI (11.88Gbps). The integrated clock restorer attenuates high frequency jitter and completely regenerates data with a pure low jitter clock. The clock restorer's loop filter is adjustable and optional external capacitors are available to reduce the CDR loop bandwidth.
