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.

Functions
• SCF-based adjustment-free 76-kHz bandpass filter
• VICS decoder circuit
• MSK delay detection circuit based on a 1T delay
• Error correction function based on a 2T delay (in the MSK detector stage)
• Digital PLL based clock regeneration circuit
• Shift-register type 1T and 2T delay circuits
• Block and frame synchronization detection circuit
• Function for setting the number of allowable BIC errors, the number of synchronization protection.
• Error correction using (272, 190) codes
• Layer 4 CRC code checking circuit
• On-chip frame memory and memory control circuit for vertical correction
• 7.2-MHz crystal oscillator circuit
• Two power saving functions (Standby and EC stop)
