Demodulator meets NorDig unified standards for terrestrial DTV

Zarlink Semiconductor recently launched what the company calls the industry's first terrestrial digital television (DTV) demodulator to fully comply with the NorDig Unified 1.0.2 standard. Featuring an on-chip RF signal strength indicator and digital intermediate frequency (IF) filter, the ZLTM10353 upgrades the performance of the company's MT352 demodulator, allowing customers to reduce costs and save board space in their DTV designs. The ZL10353 is a drop-in replacement for MT352 applications.

The ZL10353 chip is suited for set-top boxes, terrestrial network interface modules, hand-held devices, personal video recorders, and PC-TV computer cards/modules that receive DVB-T terrestrial signals.

The integrated digital IF filter demodulator eliminates the need for switched bandwidth SAW (surface acoustic wave) filters in the tuner design. This feature allows compliant reception of 6-, 7-, or 8-MHz channels using one filter.

The ZL10353 device is available now in a compact 64-pin LQFP measuring 10 by 10 mm. For more information, visit dtv.zarlink.com.
