Ordering number : EN5876 CMOS IC LC72709E, 72709W FM Multiplex Reception IC for Mobile Systems Overview The LC72709E is a data demodulation IC for receiving FM multiplex broadcasts for mobile receivers in the DARC format. This IC includes a built-in bandpass filter that extracts the DARC signal from the FM baseband signal. Since this IC supports all of the FM multiplex broadcast frame structures (methods A, A', B, and C) from the ITU-R remendations, it is optimal for use in radios for worldwide use that support FM multiplex reception. Package Dimensions unit: mm 3148-QIP44MA [LC72709E] Functions - SCF-based adjustment-free 76-k Hz bandpass filter - Support for the FM multiplex broadcast frame structures (methods A, B, and C) using serial data control. - 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) SANYO: QIP44MA unit: mm 3190-SQFP64 [LC72709W] SANYO: SQFP64 - CCB is a trademark of SANYO ELECTRIC CO., LTD. - CCB is SANYO’s original bus format and all the bus addresses are controlled by SANYO.
