www.DataSheet4U.com ® 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) .
