LMH0344  
3Gbps HD/SD SDI Adaptive Cable Equalizer  
General Description  
Features  
The LMH0344 3Gbps HD/SD SDI Adaptive Cable Equalizer  
is designed to equalize data transmitted over cable (or any  
media with similar dispersive loss characteristics). The equal-  
izer operates over a wide range of data rates from 143 Mbps  
to 2.97 Gbps and supports SMPTE 424M, SMPTE 292M,  
SMPTE 344M, and SMPTE 259M.  
SMPTE 424M, SMPTE 292M, SMPTE 344M, and SMPTE  
259M compliant  
Supports DVB-ASI at 270 Mbps  
High data rates: 143 Mbps to 2.97 Gbps  
Equalizes up to 120 meters of Belden 1694A at 2.97 Gbps,  
up to 140 meters of Belden 1694A at 1.485 Gbps, or up to  
350 meters of Belden 1694A at 270 Mbps  
The LMH0344 implements DC restoration to correctly handle  
pathological data conditions. The equalizer may be driven in  
either a single ended or differential configuration.  
Equalizes 0-100m of Belden 1694A at 2.97 Gbps with  
0.3 UI maximum output jitter  
Manual bypass and output mute with a programmable  
threshold  
Additional features include separate carrier detect and output  
mute pins which may be tied together to mute the output when  
no signal is present. A programmable mute reference is pro-  
vided to mute the output at a selectable level of signal degra-  
dation.  
Single-ended or differential input  
50Ω differential outputs  
Single 3.3V supply operation  
280mW typical power consumption with 3.3V supply  
Footprint compatible with the LMH0044  
Replaces the Gennum GS2974 or GS2974A  
Applications  
SMPTE 424M, SMPTE 292M, SMPTE 344M, and SMPTE  
259M serial digital interfaces  
Serial digital data equalization and reception  
Data recovery equalization
