Features SMPTE 259M and SMPTE 344M compliant Supports DVB-ASI at 270 Mbps Data rates: 125 Mbps to 540 Mbps Equalizes up to 350 meters of Belden 1694A at 270 Mbps Manual bypass, cable length indicator, and output mute Single-ended or differential input 50Ω differential outputs Single 3.3V supply operation Industrial temperature range: −40°C to +85°C 198 mW typical power consumption with 3.3V supply Footprint compatible with the LMH0034 and the GS9064 Description The LMH0024 SMPTE 259M / 344M 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 540 Mbps and supports SMPTE 259M and SMPTE 344M. The LMH0024 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 mute pin which can be used to manually mute the output and a cable length indicator which determines the amount of cable being equalized. Applications SMPTE 259M and SMPTE 344M serial digital interfaces Serial digital data equalization and reception Data recovery equalization

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.
