LC72707E
FM Multiplex Receiver IC Supporting
All Worldwide Standards
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 compact 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 recommendations, 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.
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)

• 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
• Conforms to the DRIS format of Digital DJ Incorporated
