Philips Semiconductors
Quadrature demodulator controller
Preliminary specification
TDA8041H
FEATURES
Generates all control signals for Quadrature Phase-Shift
Keying (QPSK) and Binary Phase-Shift Keying (BPSK)
demodulation
Can be used in applications with low Eb/No and high
symbol rate (up to 30 × 106 symbols/s)
Digital I and Q outputs (3 bits) for soft decision within
error correction
Two matched analog-to-digital converters to quantize
the I and Q signals
A digital detector for each control loop to generate the
required control signals
Digital-to-analog converters and operational amplifiers
to allow high flexibility for loop time constants
Special input stage to interface with the voltage
controlled crystal oscillator
Positive 5 V supply voltage.
APPLICATIONS
Demodulation of BPSK and QPSK modulated signals in
satellite and telephone applications.
