MSM6926GS-K数据手册OKI中文资料规格书

描述 Description

GENERAL DESCRIPTION
The MSM6926 and the MSM6946 are OKI's 300 bps single chip modem series which transmit and receive serial, binary data over a switched telephone network using frequency shift keying (FSK). The MSM6926 is compatible with ITU-T V.21 series data sets, while the MSM6946 is compatible with Bell 103 series data sets. These devices provide all the necessary modulation, demodulation, and filtering required to implement a serial, asynchronous communication link. OKI's single chip modem series is designed for users who are not telecommunication experts and are easy to use cost effective alternative to standard discrete modem design. CMOS LSI technology provides the advantages of small size, low power, and increased reliability.
The design of the integrated circuit assures compatibility with a broad base of installed low speed
modems and acoustic couplers.  Applications include interactive terminals, desk top computers,
point of sale equipment, and credit verification systems.FEATURES
