AK2363屬于集成電路（IC）的電信。由旭化成微電子株式會社制造生產(chǎn)的AK2363電信電信接口集成電路 (IC) 為通信網(wǎng)絡(luò)接口提供特定功能和控制，例如以太網(wǎng)切換、線路驅(qū)動器、ISDN、放大器、通道擴(kuò)展器、數(shù)字鎖相環(huán)、DTMF、音頻發(fā)生器和解碼器、回聲消除、檢測器和發(fā)生器、DDA、電話線路監(jiān)控器和主叫號碼標(biāo)識。

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.
