Features • SMPTE 292M, SMPTE 344M and SMPTE 259M compliant • Supports DVB-ASI at 270 Mbps • Data rates: 125 Mbps to 1.485 Gbps • Equalizes up to 200 meters of Belden 1694A at 1.485 Gbps or up to 400 meters of Belden 1694A at 270 Mbps • Manual bypass, cable length indicator, and output mute with a programmable threshold • Single-ended or differential input • 50Ω differential outputs • Single 3.3V supply operation • 208mW typical power consumption with 3.3V supply • Replaces the GS1524 and GS1524A Description The LMH0034 SMPTE 292M / 259M adaptive cable equalizer is a monolithic integrated circuit 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 125 Mbps to 1.485 Gbps 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. Applications • SMPTE 292M, SMPTE 344M, and SMPTE 259M serial digital interfaces • Serial digital data equalization and reception • Data recovery equalization

Reliability Metrics

Part Number	Process	EFR Reject	EFR Sample Size	PPM	LTA Rejects	LTA Device Hours	FITS	MTTF (Hours)
LMH0034MA	BICMOS8B+	0	1152	0	0	743900	5	211083656

Note: The Early Failure Rates (EFR) were calculated as point estimate PPM based on rejects and sample size for EFR. The Long Term Failure Rates were calculated at 60% confidence using the Arrhenius equation at 0.7eV activation energy and derating the assumed stress temperature of 150°C to an application temperature of 55°C.
