Overview

The AK2363 is a radio signaling LSI device into which an MSK modem and a DTMF Receiver are integrated on a single chip.

The MSK modem supports 1200 and 2400 bit/s, and the demodulator has a 16-bit frame pattern detection function that allows any settings. When the signal-to-noise (S/N) ratio is 12dB, the BER characteristic at 1200 bit/s is 5.0E-06, and the BER characteristic at 2400 bit/s is 1.0E-04.

The DTMF Receiver operates in two modes: Normal mode (AGD Disable) indicating input signal detection levels ranging from -27dBx to 0dBx and high sensitivity mode (AGC Enable) in which the receiver operates at –40dBx to 0dBx.
