The LMH0034MA/NOPB is an Adaptive Cable Equalizer for equalizing data transmitted over cable (or any media with similar dispersive loss characteristics). The equalizer operates over a wide range of data rates from 125Mbps to 1.485Gbps and supports SMPTE 292M, SMPTE 344M and SMPTE 259M. 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.
● SMPTE 292M, SMPTE 344M and SMPTE 259M Compliant
● Supports DVB-ASI at 270Mbps
● Manual bypass, cable length indicator and output mute with a programmable threshold
● Single-ended or differential input operation
● 50R Differential outputs
● 208mW Typical power consumption
● Green product and no Sb/Br
●Device has limited built-in ESD protection. The leads should be shorted together or the device placed in conductive foam during storage or handling to prevent electrostatic damage to the MOS gates.
