Description
The CE6313 is a QPSK/BPSK 1 - 45 MSps
demodulator and channel decoder for digital satellite
television transmissions to the European Broadcast
Union ETS 300 421 specification. It receives analogue
I and Q signals from the tuner, digitises and digitally
demodulates this signal, 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
CE6313 also provides automatic gain control to the RF
front-end device.
The CE6313 has a serial 2-wire bus interface to the
control microprocessor. Minimal software is required to
control the CE6313 because of the built in automatic
search and decode control functions.
