Overview
Ordering number : EN5875 CMOS IC LC72708E FM Multiplex Broadcast Reception IC for Mobile VICS Systems Overview The LC72708E is a data demodulation IC for receiving FM multiplex broadcasts for mobile receivers in the DARC format.
The LC72708E also includes a built-in decoder circuit that performs VICS data processing.
This allows this IC to implement compact high-functionality VICS reception systems.
Note that a contract with VICS Center is required to evaluate samples of this IC or to mass produce products that support the VICS system.
