300 bps Single Chip FSK MODEM

GENERAL DESCRIPTION

The MSM6926 and the MSM6946 are OKI's 300 bps single chip modem series which transmit and

receiveserial,binarydataoveraswitchedtelephonenetworkusingfrequencyshiftkeying(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'ssinglechipmodemseriesisdesignedforuserswhoarenottelecommunicationexpertsand

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.

Thedesignoftheintegratedcircuitassurescompatibilitywithabroadbaseofinstalledlowspeed

modems and acoustic couplers. Applications include interactive terminals, desk top computers,

point of sale equipment, and credit verification systems.
