TDA8051 - NXP

TDA8051 QPSK receiver

TDA8051 This TDA8051 is a monolithic bipolar IC intended for Quadrature Phase Shift Key (QPSK) demodulation. It includes: • Low noise RF and gain controlled amplifier • Two matched mixers • Symmetrical Voltage Controlled Oscillator (VCO) with 0 to 90° signal generator whose frequency is controlled by an integrated Phase Lock Loop (PLL) circuit. • Two match.

Features

• High operating input sensitivity
• Gain controlled amplifier
• PLL controlled carrier frequency
• Low crosstalk between I and Q channel outputs
• 3-wire transmission bus
• 5 V supply voltage. APPLICATIONS
• BPSK/QPSK demodulation. GENERAL DESCRIPTION TDA8051 This TDA8051 is a monolithic bipolar IC intended for Quadrature Phase Shift Key (QPSK) demodulation. It includes:
