LC72707E Datasheet | SANYO

Overview The LC72707E 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 LC72707E can form a pact yet high-functionality FM multiplex reception system. This IC provides built-in DRIS system data processing decoder for Digital DJ CO.,LTD. Since supporting all the FM multiplex frame structures (methods A, A’, B, and C) in the ITU-R remendations, this IC is optimal for use in radios for FM multiplex system. Note that a contract with Digital Incorporated is required to evaluate this IC and to produce end products that support DRIS. - 7.2-MHz crystal oscillator circuit - Conforms to the DRIS format of Digital DJ Incorporated Package Dimensions unit: mm 3148-QFP44MA [LC72706E] Applications - Receivers for DARC format mobile receiver FM multiplex broadcasts - FM multiplex receiver for the worldwide DRIS system of Digital DJ Incorporated. 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 - 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. - DRIS is an abbreviation of Digital DJ Radio Information Services. - DRIS is an FM multiplex broadcasts mobil receiving system which supports not only one-to-multiplex transmission but one-to-one information trans mission.
