Philips Semiconductors
Quadrature demodulator
Objective specification
TDA8040T
FEATURES
+5 V supply voltage
Bandgap internal reference voltage
Low crosstalk between I (in-phase) and Q (quadrature)
channel outputs
High operating input sensitivity
High Carrier-to-Noise Ratio (CNR) of the VCO.
APPLICATIONS
Quadrature Phase Shift Keying (QPSK) demodulation.
GENERAL DESCRIPTION
The TDA8040T is a monolitic bipolar IC dedicated for
quadrature demodulation.
It has been designed to operate in conjunction with the
TDA8041H to provide a complete QPSK demodulator.
The design of this circuit has been optimized to provide the
best quadrature accuracy necessary for digital receiver
applications and particularly for digital television.
The TDA8040T includes two matched mixers, an
RF amplifier, a symmetrical Voltage Controlled Oscillator
(VCO), a frequency divider and two matched amplifiers.
Two external filters are required for the baseband filtering.
The VCO requires an external LC tank circuit with two
varicap diodes. This oscillator operates at twice the
IF carrier frequency and can be used in a carrier recovery
AFC loop.
