Features, Applications

Preliminary specification File under Integrated Circuits, IC03 November 1994

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 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. QUICK REFERENCE DATA SYMBOL VDD(A) VDDA(C) VDD(I/O) VDDD VDD(C) IDD(tot) VIQ Rsym IO(DAC) PARAMETER supply voltage for operational amplifiers (pin 5) analog supply voltage for converters (pin 20) supply voltage for digital inputs/outputs (pin 30) supply voltage for digital section (pin 35) supply voltage for digital part of ADC and DAC (pin 42) total supply current I and Q input voltage symbol rate DAC output current VDD 5 V CONDITIONS MIN. TYP. APPLICATIONS

Demodulation of BPSK and QPSK modulated signals in satellite and telephone applications.
