1200 bps Single Chip FSK MODEM
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.
