TDA8060TS

The direct conversion QPSK demodulator of the TDA8060TS 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 as the future SMA-TV US standard.

Accurate QPSK demodulation of the TDA8060TS 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, to a certain extent, on the external filter used in the application.

Optimum signal level of the TDA8060TS 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 of the TDA8060TS 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.
