Thomson unveils DTV reference demodulator designs

MANHASSET, N.Y. - France-based digital media and video company Thomson
has unveiled two front-end digital TV reference designs based on the
company's first digital TV chips for the merchant market. The
demodulator designs, developed by Thomson Silicon Components (TSC), a
subsidiary of the company's Technology division, are based on the
company's recently introduced Vlink 4110C and VSBlink 4111A DTV
front-end ICs for digital televisions and set-top boxes. Each IC
includes a vestigial sideband (VSB) demodulator for digital terrestrial
transmission and a quadrature amplitude modulation (QAM) demodulator for
digital cable.

The Vlink IC reduces the need for additional external components by
including a digital implementation of an NTSC/BTSC demodulator
(including industry-leading signal-to-noise ratio) and an out-of-band
demodulator for digital cable-ready applications.

Both the Vlink and VSBlink chips are in production and comply with the
Advanced Television Systems Committee (ATSC) A74 guidelines and
CableLabs specifications.

The complete front-end reference design can be used as a daughter card
or can be easily integrated into a motherboard, and is the first in a
series that Thomson is developing to address key DTV feature sets. The
designs and ICs together enable various DTV feature combinations,
including digital and analog terrestrial; digital and analog cable; and
digital, cable-ready applications.
