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.
The VP310 has a serial I虏C port interface to the control microprocessor. Minimal
software is required to control the VP310 because of the built in automatic search and
decode control functions.
