CMOS IC

LC72706E

FM Multiplex Receiver IC Supporting

All Worldwide Standards

Overview

The LC72706E is a data demodulation IC for receiving

FM multiplex broadcasts for mobile receivers in the

DARC format. In conjunction with a bandpass filter IC

(either the LV3400M or the LV3403M), the LC72706E

can form a compact yet high-functionality FM multiplex

reception system. This IC supports all the FM multiplex

frame structures (methods A, B, and C) in the ITU-R

recommendations.
