MSM9564
IC for FM Multiplex Data Demodulation
GENERAL DESCRIPTION
TheMSM9564isanICwhichdemodulatesFMcharactermultiplexsignalsintheDARC(DataRadio
*1
Channel) format to obtain digital data. The MSM9564 operates at 5 V.
The MSM9564 contains on one chip a band pass filter using a switched capacitor filter (SCF) and a
group of circuits including frame memory, a frame synchronization circuit, and an error correction
circuit.
ByconnectinganexternalFMreceiverandmemoryfortemporarydatastorage,andmicrocontroller,
a system for obtaining digital data can easily be constructed.
The FM multiplex demodulation ICs, the MSM9500-series devices, are configured with minimum
functions; so they will, by changing the software of the external microcontroller, be able to respond
flexibly to the many FM multiplex broadcast services that are going to come about in the future.
The MSM9564 is best suited to radios and information processing devices that support DARC FM
multiplex broadcasting. It is also best suited to car radios and car navigation systems that support
VICS (Vehicle Information and Communication System), which started its service in 1996.
*1 DARC is a registered trademark of NHK Engineering Services.
Any manufacturer who has a contract with NHK Engineering Services can produce and sell
electronic equipment utilizing the DARC technology.
Any manufacturer who has a contract with NHK Engineering Services and VICS Center can
produce and sell electronic equipment utilizing the VICS technology.

Peak values (a total voltage of the following signals (a) to (c)) of composite signals including
multiplex signals.
(a) Voice signals (100% modulated: voice max.)
(b) Pilot signal
(c) FM multiplex signals (10%: LMSK max.)
The maximum amplitude of an input signal is in the range of 2.0 V in which the internal
P-P
IC circuit is not saturated.
Therefore, multiplex signals of up to 2.0 V can be input if only multiplex signals(excluding
P-P
composite signals) are input from a signal generator.

Notes for Mounting the Surface Mount Type Package
The SOP, QFP, TSOP, TQFP, LQFP, SOJ, QFJ (PLCC), SHP, and BGA are surface mount type
packages, which are very susceptible to heat in reflow mounting and humidity absorbed in
storage. Therefore, before you perform reflow mounting, contact Oki’s responsible sales person
ontheproductname,packagename,pinnumber,packagecodeanddesiredmountingconditions
(reflow method, temperature and times).
