Satellite ZERO-IF QPSK down-converter
Product specification
TDA8060ATS
FEATURES
Direct conversion Quadrature Phase Shift Keying
(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 3 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.
The 920 to 2200 MHz wide range oscillator covers
American, European and Asian satellite bands as well as
the 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 pin AGC sets the gain for
both I and Q channels, providing a 37 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.
