STMicroelectronics DTTI5516XWC
The DTTi5516 is an integrated demodulator/ decoder solution for digital terrestrial receivers for compressed video, sound and data services. 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.DESCRIPTION
. A COFDM (coded orthogonal frequency division multiplex) demodulator performs IF to MPEG-2 block processing of OFDM carriers. 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.
