GENERAL DESCRIPTION
This TDA8051 is a monolithic bipolar IC intended for
Quadrature Phase Shift Key (QPSK) demodulation. It
includes:
The gain control is produced by output level detection
compared with an external pre-fixed reference. The PLL
consists of:
PACKAGE
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 matched amplifiers for output base-band active
filtering and output buffers
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
