MSM6927/6947 General Description
The MSM6927 and the MSM6947 are OKI's 1200 bps single chip modem series which transmit and receive serial, binary data over a switched telephone network using frequency shift keying(FSK).
The MSM6927 is compatible with ITU-T V.23 series data sets, while the MSM6947 is compatible with Bell 202 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.
