Semiconductor MSM9565
IC for FM Multiplex Data Demodulation
This version: Mar. 1999 MSM9565
Pr el ar in im y
GENERAL DESCRIPTION
The MSM9565 is an IC which demodulates FM character multiplex signals in the DARC (Data Radio Channel)*1 format to obtain digital data. The MSM9565 operates at 3.3 V. The MSM9565 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. By connecting an external FM receiver and memory for temporary data storage, and microcontroller, 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 MSM9565 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 0.9 VP-P in which the internal IC circuit is not saturated. Therefore, multiplex signals of up to 0.9 VP-P can be input if only multiplex signals (excluding composite signals) are input from a signal generator.
