QAMI5516 Datasheet - STMicroelectronics

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.
