MSM9563 - IC for FM Multiplex Data Demodulation

General Description

The MSM9563 is an IC which demodulates FM character multiplex signals in the DARC (Data Radio Channel)

1 format to acquire digital data.

The MSM9563 operates at 3 V.

Key Features

  • Built-in two receive channels including main channel and sub-channel (one of two FM stations can be selected).
  • Internal frame memory enables automatic error correction.
  • Built-in bandpass filter (SCF).
  • Built-in block synchronization circuit and frame synchronization circuit.
  • The number of synchronization protecting steps can be set.
  • Regeneration of data clocks by digital PLL.
  • 1T delay detector.
  • Built-in error correcting cir.

MSM9563 IC for FM Multiplex Data Demodulation FEDL9563-03 Issue Date: Nov. 7, 2011 GENERAL DESCRIPTION The MSM9563 is an IC which demodulates FM character multiplex signals in the DARC (Data Radio Channel)*1 format to acquire digital data. The MSM9563 operates at 3 V. In the DARC format, baseband signals at ordinary FM broadcasting frequencies are multiplexed with 16 kbps digital data which is L-MSK-modulated at 76 kHz. The MSM9563 has a bandpass filter consisting of an SCF, frame synchronization circuit, and error correction circuit on a single chip. They allow a system for acquisition of digital data to be easily constructed by externally mounting an FM receiver tuner, microcontroller for control, and memory for temporary storage of data.
