LC72706E

Ordering number : EN5745 CMOS IC LC72706E FM Multiplex Receiver IC Supporting All Worldwide Standards Overview The LC72706E is a data demodulation IC for receiving FM multiplex broadcasts for mobile receivers in the DARC format. In conjunction with a bandpass filter IC (either the LV3400M or the LV3403M), the LC72706E can form a compact yet high-functionality FM multiplex reception system. This IC supports all the FM multiplex frame structures (methods A, B, and C) in the ITU-R recommendations. Package Dimensions unit: mm 3148-QFP44MA [LC72706E] 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 Serial control data transfer based support for the A, B, and C FM multiplex frame structures 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 SANYO: QFP44MA CCB is a trademark of SANYO ELECTRIC CO., LTD.
