Single module demodulator and decoder IC for digital video set-top boxes
DATA BRIEF
Description
. The DTTi5516 is an integrated demodulator/ decoder solution for digital terrestrial receivers for compressed video, sound and data services. A COFDM (coded orthogonal frequency division multiplex) demodulator performs IF to MPEG-2 block processing of OFDM carriers. The demodulated stream is then processed by video and audio decoders using standard Omega technology. The DTTi5516 provides a cost-effective solution for a digital video set-top boxes using a 2-layer PCBs and single device. It also has lower power requirements than separate demodulator and decoder ICs. The DTTi5516 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.
