FM Multiplex Receiver IC for VICS Systems
Overview
The LC72705E is a data demodulation IC for receiving
FM multiplex broadcasts for mobile receivers in the
DARC format. This IC includes a decoder circuit that
performs the required VICS processing, and, in
conjunction with a bandpass filter IC (either the
LV3400M or the LV3403M), can form a compact yet
high-functionality VICS reception system. Note that a
contract with VICS Center is required to evaluate this IC
and to produce end products that support VICS.
Applications
• Receivers for DARC format mobile receiver FM
