LC72705E

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. unit: mm 3148-QFP44MA [LC72705E] Applications Receivers for DARC format mobile receiver FM multiplex broadcasts Functions 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 states 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 VICS decoder circuit SANYO: QFP44MA Package Dimensions CCB is a trademark of SANYO ELECTRIC CO., LTD.
