STV0299

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 DSSTM specifications. Processing is fully digital. 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 of STV0299 can be selected through a bank of control/configuration registers via an I2C or parallel bus. The chip outputs MPEG 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.
