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)
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
Conforms to the DRIS format of Digital DJ Incorporated
