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.
● 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
