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.
