TDA8060TS; Satellite ZERO-IF QPSK down-converter
| Description |  |
The direct conversion QPSK demodulator is the front-end receiver dedicated to digital TV broadcasting, satisfying both DVB and DBS TV standards. The 920 to 2200 MHz wide range oscillator covers American, European and Asian satellite bands as well the future SMA-TV US standard. Accurate QPSK demodulation is ensured by the on-chip loop-controlled phase shifter. The Zero-IF concept discards traditional IF filtering and intermediate conversion techniques. It also simplifies the signal path. The baseband I and Q signal bandwidth only depends, a certain extent, on the external filter used in the application. Optimum signal level is guaranteed by a gain-controlled amplifier at the RF input. The GAIN pin sets the gain for both I and Q channels, providing a 30 dB range. The chip also offers a selectable internal LO prescaler (divide-by-2) and buffer that has been designed to be compatible with the input of a terrestrial or satellite frequency synthesizer.
