L64781 Single-Chip COFDM Receiver

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.

The L64781 interfaces seamlessly 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

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.

The L64781, LSI Logic’s fully integrated single-chip COFDM demodulator, is fully

compliant to the DVB-T standard for digital terrestrial television in Europe
