-40oC to +85oC
Description
The ZL10210 is a DVB-C and ITU-T annex A/C QAM
demodulator. This low power cable demodulator
includes standard Zarlink features of auto signal acqui-
sition, 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 BoM (bill of materials) in cost
sensitive applications. The device is packaged in a
7 x 7 mm 64-pin LQFP.
Functional Description
The ZL10210 accepts an analog signal from the tuner,
either at low Intermediate Frequency (IF) or conven-
tional IF up to 50 MHz, and delivers an MPEG2
compliant transport stream. It contains a single 10-bit
