INTEGRATED CIRCUITS DATA SHEET TDA8060TS Satellite ZERO-IF QPSK down-converter Product specification Supersedes data of 1998 May 29 File under Integrated Circuits, IC02 1999 Aug 30 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 deSupersedes data of 1998 May 29 modulation. GENERAL 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 QUICK REFERENCE DATA SYMBOL VCC ∆Φ fosc Vo(p-p) Tamb supply voltage quadrature error oscillator frequency output voltage (peak-to-peak value) operating ambient temperature PARAMETER MIN. 4.75 − 920 − −20 TDA8060TS 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 depen...
