INTEGRATED CIRCUITS DATA SHEET TDA8060TS Satellite ZERO-IF QPSK down-converter Product specification Supersedes data of 1999 Aug 30 File under Integrated Circuits, IC02 1999 Nov 11 Philips Semiconductors Product specification Satellite ZERO-IF QPSK down-converter FEATURES · Direct conversion QPSK demodulation (Zero IF) · 920 to 2200 MHz range · On-chip loop-controlled 0 or 90° phase shifter · Variable gain on RF input · 60 MHz, at -1 dB, bandwidth for baseband I and Q amplifiers · Local oscillator output to PLL satellite or terrestrial · 5 V supply voltage. APPLICATIONS · Direct Broadcasting Satellite (DBS) QPSK demodulation · Digital Video Broadcasting (DVB) QPSK demodulation. GENERAL DESCRIPTION The direct conversion QPSK demodulator is the front-end receiver dedicated to digital TV broadcasting, satisfying both DVB and DBS TV standards. QUICK REFERENCE DATA SYMBOL VCC fosc Vo(p-p) Tamb supply voltage quadrature error oscillator frequency output voltage (peak-to-peak value) ambient temperature PARAMETER MIN. 4.75 - 920 - -20 TDA8060TS 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 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 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.
