Zarlink demodulator terrestrial television applications for portable TV reception

Zarlink (Zarlink) introduced a new semiconductor company for PC-TV, handheld digital television (DTV) and MT90820AP datasheet and portable applications, terrestrial demodulator - ZL10355. The device fully comply with stringent NorDig Unified 1.0.2 standard. ZL10355 chip and MT90820AP price and pin and MT90820AP suppliers and features compatible with the recently introduced ZL10353 device, which provides the lowest operating and standby power consumption NorDig Unified, and the fastest DVB-T "blind scan and auto re-acquisition" function, package size is 7 × 7mm.

ZL10355 includes an integrated digital intermediate frequency (IF) filter in the tuner design, the bandwidth SAW filter switch is omitted, making the filter is compatible with a single receiver 6MHz, 7MHz or 8MHz channel. The chip also includes a RF signal strength indicator to the receiver box to download and read directly on the TV signal strength.

The ZL10355 chip can work in small -40 ℃ to 85 ℃ for the extended temperature range, power consumption is less than the typical application 300mW, in low power mode to 270mW, help reduce power consumption to meet mandatory requirements and portable and PC-TV equipment manufacturers of power requirements.

Zarlink demodulator with very high-speed blind scan and auto re-acquisition function, it is a hardware-based state machine that automatically scans the entire broadcast band, than software-based algorithm is much faster channel scanning. Because in the PC and handheld TV devices to receive, when the user moves around, the device swinging back and forth, so high-speed scanning and channel re-acquisition is a very useful feature.

New ZL10355 demodulator is available from stock. In addition, the company also offers a complete evaluation system, including terrestrial television interface module (TNIM) reference design, evaluation software, PC interface and device drivers.
