Fully-integrated solution enables less-complex,
low-cost cable modems and cable-TV set-top boxes
Significantly increases channel capacity
Variable data rates enable systems to adapt to
channels encoded at different data rates
Integrated A/D converter reduces system
manufacturing costs and complexity
A universal chip solution that supports DVB, DAVIC,
ITU-T J.83/Annex A and Annex C, IEEE 802.14-based
systems
Digital adaptive equalizers ensure robust performance
in the presence of multipath reflections
