MSM9560/MSM9561
GENERAL DESCRIPTION
The MSM9560/MSM9561 is an IC which demodulates FM character multiplex signals in the DARC
(Data Radio Channel)
*1
format to obtain digtal data. The MSM9560 operates at 4.5 to 5.5 V and the
MSM9561 at 1.8 to 3.3 V. In the DARC system, 16 kbps of digital data L-MSK modulated at 76 kHz
is multiplexed on an ordinary FM broadcast base band signal.
The MSM9560/MSM9561 contains on one chip a band pass filter using a switched capacitor filter
(SCF) and a group of circuits including a frame synchronization circuit and an error correction circuit.
By connecting an external FM receiver and memory for temporary data storage and by controlling
them by the CPU, a system for obtaining digtal data can easily be constructed.
The FM multiplex demodulation ICs, the MSM9500-series devices, are configured with minimum
functions; so they will, merely by making changes to the software of the external microcomputer, be
able to respond flexibly to the many FM multiplex broadcast services that are going to come about
in the future.
The MSM9560/MSM9561 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, and
the MSM9561 is especially suited to portable equipment.
