Overview
Ordering number : EN5744 CMOS IC LC72705E 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.
