Product Summary
The LMH0034MA is a adaptive cable equalizer. The LMH0034MA adaptive cable equalizer is a monolithic integrated circuit for equalizing data transmitted over cable (or any media with similar dispersive loss characteristics). The equalizer LMH0034MA operates over a wide range of data rates from 143 Mbps to 1.485 Gbps and supports SMPTE 292M, SMPTE 344M and SMPTE 259M. The LMH0034MA implements DC restoration to correctly handle pathological data conditions. DC restoration can be bypassed for low data rate applications. The equalizer LMH0034MA 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.
