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)
