STV0900

Multistandard advanced dual demodulator

for Satellite Digital TV and Data services set-top boxes

Description

The STV0900 features a high speed DVB-S2 Forward Error Corrector (FEC) which is designed to handle

up to 180 Mega Channel bits per second at its input. To feed the FEC the STV0900 implements two

identical demodulators, each capable of handling QPSK legacy, DVBS2 constant coding and modulation

for satellite broadcast and Advanced Coding and Modulation for interactive services. The STV0900

supports mode switching on a frame basis without synchronization or data loss.

Features
