QAMi5516
Single module demodulator and decoder IC
for digital video set-top boxes
DATA BRIEF
Description
The QAMi5516 is an integrated demodulator/decoder
solution for digital cable receivers for compressed
video, sound and data services. A QAM demodulator
performs IF to MPEG-2 block processing of QAM
carriers. The demodulated stream is then processed
by video and audio decoders using standard Omega
technology.
The QAMi5516 contains all of the most commonly
used descramblers, and thus allows a single
platform to be developed to cover the entire
mainstream set-top box market (USA, Europe, Asia)
.
