This low power cable demodulator includes standard Zarlink features of auto signal acquisition, fast blind-scan capability, software/hardware power down, RF level, BER and SNR detection. The ZL10210 represents the latest in QAM demodulation for DVB cable. Together with a cable tuner, a full digital cable receiver front-end can be realized. Either conventional intermediate frequencies such as 36 or 44 MHz or low intermediate frequencies can be used see application below. The ZL10210 requires only a single channel filter bandwidth of 8 MHz nominal for full DVB and ITU-T annex A/C performance. The low power consumption, small package form factor and integrated software/hardware power-down modes help reduce the system Bo M (bill of materials) in cost sensitive applications. The device is packaged in a 7 x 7 mm 64-pin LQFP.
