Fast scan satellite demodulator IC

10 September 2003 Telecoms, Datacoms, Wireless, IoT

Zarlink Semiconductor has added what it claims is the industry's fastest-scanning, lowest-power channel demodulator to its family of RF chips for digital satellite TV systems. The ZL10312 device, combined with Zarlink's SL1925/1935 tuner chips, offers manufacturers a complete RF subsystem for tuning, scanning, decoding, and demodulating digital satellite TV signals. The ZL 10312 chip is aimed primarily at STBs sold in Asia and the Middle East that receive 'free-to-air' digital TV channels on satellite broadcast bands. The demodulator is also suitable for the European and US satellite STB markets. The chip supports QPSK (quaternary phase shift keying) and BPSK (bipolar phase shift keying) modulation schemes, and uses advanced digital filters to detect and decode symbol rates. It is claimed to be the lowest-power chip in its class, with consumption of only 300 mW. It is packaged in 7 by 7 mm 64-pin LQFP.
