Lsi Devices For Fm Multiplex Data Demodulation

The MSM9554 and MSM9555 are LSI devices which demodulate FM character multiplex signals in the DARC (DAta Radio Channel)*1 format to acquire digital data. The MSM9554 and MSM9555 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 MSM9554 and MSM9555 has a bandpass Filter consisting of SCF, frame synchroniza- tion circuit, and error correction circuit, on a single chip. By Oki Semiconductor
