MSM9552 General Description
The MSM9552 and MSM9553 are LSI devices which demodulate FM character multiplex signals in the DARC (DAta Radio Channel)* format to acquire digital data. The MSM9552 and MSM9553 operate on 5V and 3V, respectively. In the DARC format, baseband signals at ordinary FM broadcasting frequencies are multiplexed with 16k-bps digital data which are L-MSK-modulated at 76kHz.
Each of the MSM9552 and MSM9553 has a bandpass filter consisting of SCF, frame synchronization circuit, error correction circuit, etc. on a single chip.So, a system for acquisition of digital data can be easily constructed by externally mounting an FM receiver tuner, microcontroller for control, and memory for temporary storage of data.
The MSM9552 and MSM9553 have a simple configuration, and are equipped with only necessary functions. By making changes to software for the external microcontroller, the MSM9552 and MSM9553 can meet the various requirements of FM multiplex broadcasting services which will be offered in future.
These LSI devices are best suited to the radio sets and information devices for FM character multiplex broadcasting, which started in Japan in October 1994. Especially, the MSM9553 is suitable for portable units.
