LMH0344  
3 Gbps HD/SD SDI Adaptive Cable Equalizer  
General Description  
Features  
The LMH0344 3 Gbps 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 125 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  
Wide range of data rates: 125 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  
400 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 0-120m 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 (internal 50pullups)  
Single 3.3V supply operation  
The device is available in two space–saving packages: a 4 X  
4 mm 16-pin LLP and even more space–efficient 3 x 3 mm  
25-ball MICRO-ARRAY package.  
280 mW typical power consumption  
16-pin LLP or 25-ball MICRO-ARRAY package  
Industrial temperature range: −40°C to +85°C  
HBM ESD Rating: 8 kV  
LLP version footprint compatible with the LMH0044 and  
LMH0074  
Replaces the Gennum GS2974A or GS2974B  
Applications  
SMPTE 424M, SMPTE 292M, SMPTE 344M, and SMPTE  
259M serial digital interfaces  
Serial digital data equalization and reception  
Data recovery equalization
