STV0900
Multistandard advanced dual demodulator
for Satellite Digital TV and Data services set-top boxes
Data Brief
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
