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.
