LMH0344
LMH0344 is 3Gbps HD/SD SDI Adaptive Cable Equalizer manufactured by National Semiconductor.
Description The LMH0344 3Gbps HD/SD SDI Adaptive Cable Equalizer is designed to equalize data transmitted over cable (or any media with similar dispersive loss characteristics). The equalizer operates over a wide range of data rates from 143 Mbps to 2.97 Gbps and supports SMPTE 424M, SMPTE 292M, SMPTE 344M, and SMPTE 259M. The LMH0344 implements DC restoration to correctly handle pathological data conditions. The equalizer may be driven in either a single ended or differential configuration. Additional features include separate carrier detect and output mute pins which may be tied together to mute the output when no signal is present. A programmable mute reference is provided to mute the output at a selectable level of signal degradation. Features - SMPTE 424M, SMPTE 292M, SMPTE 344M, and SMPTE 259M pliant - Supports DVB-ASI at 270 Mbps - High data rates: 143 Mbps to 2.97 Gbps - Equalizes up to 120 meters of Belden 1694A at 2.97 Gbps, up to 140 meters of Belden 1694A at 1.485 Gbps, or up to 350 meters of Belden 1694A at 270 Mbps - Equalizes 0-100m of Belden 1694A at 2.97 Gbps with 0.3 UI maximum output jitter - Manual bypass and output mute with a programmable threshold - Single-ended or differential input - - - - - 50Ω differential outputs Single 3.3V supply operation 280m W typical power consumption with 3.3V supply Footprint patible with the LMH0044 Replaces the Gennum GS2974 or GS2974A Applications - SMPTE 424M, SMPTE 292M, SMPTE 344M, and SMPTE 259M serial digital interfaces - Serial digital data equalization and reception - Data recovery equalization Typical Application © 2007 National Semiconductor Corporation .national.
