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.

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.
