Description The ZL10313 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 descrambling function. The output is in the form of MPEG2 or DSS transport stream data packets. The ZL10313 also provides automatic gain control to the RF front-end device.
