Description

The ZL10312 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, and 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 ZL10312 also provides automatic gain control to the RF front-end device.

The ZL10312 has a serial 2-wire bus interface to the control microprocessor. Minimal software is required to control the ZL10312 because of the built in automatic search and decode control functions.
