The LMH0344 3-Gbps 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 125 Mbps to 2.97 Gbps and supports ST 424, ST 292, ST
344, and ST 259.
The LMH0344 device implements DC restoration to correctly handle pathological data
conditions. The equalizer may be driven in either a single-ended or differential
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.
For applications using the
4:4:4:4 10 bits video format, the LMH0394 cable equalizer will provide better
The device is available in two space-saving packages: a 4-mm × 4-mm 16-pin WQFN and even
more space-efficient 3-mm × 3-mm 25-ball CS-BGA package.
