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.

•

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

50Ω Differential 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

APPLICATIONS
