DVB-T Compliant Demodulation
Overview
The L64781, the second chip in LSI Logic’s family of highly integrated, high-
performance solutions for digital terrestrial TV broadcast, is a fully integrated,
single-chip COFDM (Coded Orthogonal Frequency Division Multiplex) demod-
ulator. The L64781 channel receiver is fully compliant with DVB-T standards
and follows the highly successful L64780, widely used by manufacturers producing
set-top boxes for the current European digital terrestrial market.
Proven Solution for Fast Time to Market
The completeness of this solution enables a spectrum of applications for both
2K-only broadcasting in the UK, and 8K multiple or single frequency network
broadcasting in Scandinavia, Spain and other emerging markets such as Singapore.
Its robust channel equalizer and doppler immunity also allow manufacturers to
use this solution in mobile DVB-T applications.
The L64781 comprises the COFDM demodulator, a DVB-compliant FEC decoder
and a 10-bit analog-to-digital converter. With this device, digital set-top box and
TV manufacturers have a ready-proven, high-performance technology to bring
DTT-enabled products to market quickly and cost effectively.
The L64781 is a fully variable rate demodulator, supporting 6, 7 and 8MHz
channels. The chip is highly integrated (both timing and frequency loops are
fully digital) and capable of delivering up to 31.7 Mbit/sec. This represents more
than 20 movie channels or 4 live video channels in each 8MHz channel
previously filled by a single analog PAL channel.
L64781 Single-Chip COFDM Receiver
The L64781 interfaces seamessly to a tuner
to provide an error corrected MPEG2-TS.
This gives set-top box and TV manufacturers
a complete digital terrestrial TV receiver and
enables fast time-to-market
The L64781,LSI Logic’s fully integrated single-chip COFDMdemodulator,is fully
compliant to the DVB-T standard for digital terrestrial television in Europe
