DESCRIPTION

The STV0299 Satellite Receiver with FEC is a

CMOS single-chip multistandard demodulator for

digital satellite broadcasting. It consists of two A/D

converters for I-input and Q-input, a multistandard

QPSK and BPSK demodulator, and a forward

error correction (FEC) unit having both an inner

(Viterbi) and outer (Reed-Solomon) decoder.

The FEC unit is compliant with the DVB-S and

It integrates a derotator before the Nyquist root

filter, allowing a wide range of offset tracking.

The

high

sampling

rate

facilitates

the

implementation of low-cost, direct conversion

tuners.

A variety of configurations and behaviours can be

selected through a bank of control/configuration

Transport Streams and interfaces seamlessly to

the Packet Demultiplexers embedded in ST’s

ST20-TPx or STi55xx. High sampling frequency

(up to 90MHz) considerably reduces the cost of

LPF of direct conversion tuners.

The multistandard capability associated with a

broad range of input frequency operations makes

it easy-to-use. Its low power consumption, small

package and optional serial output interface

makes it perfect for embedding into a tuner.
