双音多频发送接收器MT8870/MT8888及其应用本文介绍了双音多频(DTMF)发送接收器件MT8888的主要功能、基本组成和工作原理。
最多给出了MT8888与单片机80C32接口的硬件电路及软件程序。
1 基本功能MT8888是一种具有Intel微处理器接口的功能较强的双音多频(DTMF)发送和接收器件。
可用于寻呼系统、交换机系统和移动通信、转帐卡系统、互接拨号器、数字通信和计算机等领域。
其主要功能有：(1)完整的DTMF发送和接收功能；(2)高速Intel微处理器接口；(3)可工作于自动音频突发模式；(4)可调整保护时间；(5)呼叫音检测到-30dBm。
MT8888引脚排列如图1所示。
各引脚功能如下：图1 MT8888引脚图IN+、IN-(1，2)—运放的同相和反相输入端；GS(3)—增益选择端。
在该引脚与IN-引脚间接反馈电阻可调节运放增益；Vref(4)—基准电压输出端。
通常为VDD/2，作为运放的偏置电压；VSS(5)—芯片电源负端，接地；OSC1、OSC2(6、7)—时钟或振荡器的输入、输出端。
两引脚间接3.579545MHz晶体与内部电路构成芯片振荡器；若由外部电路提供时钟，则OSC2引脚开路；TONE(8)—DTMF信号输出端，也可通过编程设置为单音输出；(9)—微处理器写输入端，低电平有效，与TTL电平兼容；(10)—片选信号输入端，低电平有效。
该引脚可由微处理器的地址锁存信号(ALE)直接提供；RS0(11)—寄存器选择控制输入端；(12)—微处理器读输入端，低电平有效，与TTL电平兼容；/CP(13)—中断请求信号，为开漏输出。
在中断模式下，当一个有效DTMF信号突发发送或接收时，输出低电平信号。
若控制寄存器设定电路工作于呼叫处理(CALL)模式和中断使能，则该端输出代表运放输入的方波信号音，但该信号频率必须落在呼叫处理滤波器的带宽内；D0～D3(14-17)—数据总线，与TTL电平兼容。
