73M223数据手册TDK中文资料规格书

描述 Description

DESCRIPTION
The 73M223 modem device receives and transmits serial and binary data over existing telephone networks using Frequency Shift Keying (FSK). It provides the filtering, modulation, and demodulation to implement a serial, asynchronous data communication channel. The 73M223 employs the CCITT V.23 signaling frequencies of 1302 and 2097 Hz, operating at 1200 baud, and is intended for half duplex operation over a two-line system.FEATURES
