LMH0074 SMPTE 259M / 344M Adaptive Cable Equalizer  
Check for Samples: LMH0074

FEATURES  
DESCRIPTION  
The LMH0074 SMPTE 259M / 344M Adaptive Cable  
Equalizer is designed to equalize 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.  
2
SMPTE 259M and SMPTE 344M Compliant  
Supports DVB-ASI at 270 Mbps  
Data Rates: 125 Mbps to 540 Mbps  
Equalizes up to 400 Meters of Belden 1694A at  
270 Mbps  
The LMH0074 implements DC restoration to correctly  
handle pathological data conditions. The equalizer  
may be driven in either a single ended or differential  
configuration.  
Manual Bypass and Output Mute with a  
Programmable Threshold  
Single-Ended or Differential Input  
50Differential Outputs  
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 provided to mute the  
output at a selectable level of signal degradation.  
Single 3.3V Supply Operation  
Industrial Temperature Range: 40°C to +85°C  
208mW Typical Power Consumption with 3.3V  
Supply  
Footprint Compatible with the LMH0044 and  
the GS9074A
