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.
Applications
• Receivers for DARC format mobile receiver FM
multiplex broadcasts
