Qpsk Receiver - Nxp Semiconductors

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 0to90 signal generator whose frequency is controlled by an integrated Phase Lock Loop (PLL) circuit. Two matched Amplifiers for output base-band active filtering and output Buffers The gain control is produced by output level detection compared with an external pre-fixed reference. The PLL consists of: Divide by four preamplifier 12-bit programmable main divider Crystal Oscillator with 8-bit programmable reference divider Phase/frequency detector combined with Charge Pump to drive tuning Amplifier 30 V output By NXP Semiconductors
