概要

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 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.

For applications which use the RGBα data patterns, the LMH0394 cable equalizer will provide better performance.

The device is available in two space–saving packages: a 4 X 4 mm 16-pin LLP and even more space–efficient 3 x 3 mm 25-ball MICRO-ARRAY package.
