LMH0044  
SMPTE 292M / 259M Adaptive Cable Equalizer  
General Description  
Features  
n SMPTE 292M, SMPTE 344M and SMPTE 259M  
compliant  
The LMH0044 SMPTE 292M / 259M adaptive cable equal-  
izer 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 143 Mbps to 1.485 Gbps and  
supports SMPTE 292M, SMPTE 344M and SMPTE 259M.  
n Supports DVB-ASI at 270 Mbps  
n High data rates: 143 Mbps to 1.485 Gbps  
n Equalizes up to 140 meters of Belden 1694A at 1.485  
Gbps or up to 350 meters of Belden 1694A at 270 Mbps  
n Manual bypass and output mute with a programmable  
threshold  
n Single-ended or differential input  
n 50differential outputs  
The LMH0044 implements DC restoration to correctly handle  
pathological data conditions (DC restoration may be by-  
passed for low data rate applications). The equalizer may be  
driven in either a single ended or differential configuration.  
Additional features include separate carrier detect and out-  
put 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.  
n Single 3.3V supply operation  
n 208mW typical power consumption with 3.3V supply  
n Replaces the GS1574 and GS1574A  
Applications  
n SMPTE 292M, SMPTE 344M, and SMPTE 259M serial  
digital interfaces  
n Serial digital data equalization and reception  
n Data recovery equalization
