【文字介紹】

The new FQD1236E/FH-5 belongs to the new family of Terrestrial TV frontends, specially developed for LCD-TV application where a low noise and high performance is required. The module is suitable for terrestrial ATSC/QAM and high performance NTSC reception. It combines the functions of an all-band TV tuner, an ATSC IF for on-board (external) VSB/QAM demodulation and an NTSC Quasi-Split Sound IF (QSS) demodulation unit. An integrated wideband AGC detector ensures optimum signal handing for both analog and digital TV reception. A power saving feature between analog and digital TV modes is built-in.
