® DTTi5516
Single module demodulator and decoder IC
for digital video set-top boxes
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.
