MSM6926/6946  
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.
