The STV0900 is a multistandard advanced dual demodulator for Satellite Digital TV and Data services set-top boxes. It features a high-speed DVB-S2 Forward Error Corrector (FEC) capable of handling up to 180 Mega Channel bits per second at its input. 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.
