QAMi5516

Single module demodulator and decoder IC

for digital video set-top boxes

®

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)

.

Application: Highly cost-effective solution for digital cable set-top boxes
