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.
