The LMH0034 is a monolithic integrated circuit that can be used to equalize data transmitted over a cable (or any media with similar dispersive loss characteristics) at data rates from 143 Mbps to 1.485 Gbps. It supports the SMPTE 292M, SMPTE 344M and SMPTE 259M standards. The LMH0034 implements DC restoration to correctly handle pathological data conditions. DC restoration can be bypassed for low data rate applications. The equalizer is flexible in allowing either single-ended or differential input drive. Additional features include a combined carrier detect and output mute pin which mutes the output when no signal is present. A programmable mute reference is used to mute the output at a selectable level of signal degradation. A cable length indicator is provided to determine the amount of cable being equalized.
