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 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 using the 4:4:4:4 10 bits video format, the LMH0394 cable equalizer will provide better performance.
●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.
