Functions

• Noise amp, noise AGC circuit, noise density circuit.

• Antenna switching trigger output circuit.

• Antenna switching T flip-flop circuit.

• Antenna holding function to be used at weak input signal
reception mode, forced antenna holding function.

Features

• "Count system"-used, reliable detection of multipath
distortion.

• One-tuner type diversity system allowing cost reduction
of sets.

• The output to hold the antenna at the weak input signal
mode and the output (antenna switching trigger output) to
indicate that the antenna switching frequency is high are
delivered at the same pin, allowing a wide variety of
applications according to the design concept of set.
