The VP310 is a QPSK/BPSK 1 to 45MBaud demodulator and channel decoder for digital satellite television transmissions to the European Broadcast Union ETS 300 421 specification. It receives analog I and Q signals from the tuner, digitises and digitally demodulates this signal, and implements the complete DVB/DSS FEC (Forward Error Correction), and de-scrambling function. The output is in the form of MPEG2 or DSS transport stream data packets. The VP310 also provides automatic gain control to the RF front-end devices.
