TDA8263HN Fully integrated satellite tuner Rev. 01 — 14 December 2004 Product data sheet 1. General description The direct conversion QPSK demodulator is the front-end receiver dedicated to digital TV broadcasting, satisfying both DVB-S and DBS TV standards. The wide range oscillator (from 950 MHz to 2175 MHz) covers the American, European and Asian satellite bands, as well as the SMA-TV US standard. The Zero-IF (ZIF) concept discards traditional IF filtering and intermediate conversion techniques. Gain-controlled amplifiers in the RF guarantee optimum signal level. The variable gain is controlled by the signal returned from the Satellite Demodulator and Decoder (SDD) and applied to pin AGC. The integrated LNA allows the IC to be directly connected to the LNB output.
