Analogue, Mixed Signal, LSI
Zarlink Semiconductor has introduced the next generation of its QPSK (quaternary phase shift keying) demodulators for digital satellite TV systems. The ZL10313 chip is targeted at DVB-S (digital video broadcasting-satellite) receivers used worldwide. This newest demodulator is fully pin-compatible with Zarlink's predecessor, and offers the same key features including 'blind scan' capability that allows STB (set-top box) users to quickly scan the complete range of available television signals with minimal intervention. The device now also directly interfaces with all common MPEG decoders and back-end STB processors. The ZL10313 demodulator, when combined with the ZL10036 tuner chip, provides a complete satellite front-end subsystem for tuning, scanning, decoding, and demodulating digital satellite TV signals.
