LMH0034 SMPTE 292M/ 259M Adaptive Cable Equalizer
Checkfor Samples: LMH0034
1FEATURES DESCRIPTIONThe LMH0034 SMPTE 292M/ 259M adaptive cable
SMPTE 292M, SMPTE 344M and SMPTE 259M equalizer is a monolithic integrated circuit for
Compliant equalizing data transmitted over cable (or any media
• Supports DVB-ASIat 270 Mbps with similar dispersive loss characteristics). The
Data Rates: 125 Mbpsto 1.485 Gbps equalizer operates overa wide rangeof data rates
from 125 Mbpsto 1.485 Gbps and supports SMPTE
• Equalizes upto 200 Metersof Belden 1694Aat 292M, SMPTE 344M and SMPTE 259M.
