MX439 MSK Modem

The MX439 is a single-chip CMOS LSI circuit which operates as a 1200 baud MSK modem. The mark and space frequencies are 1200Hz and 1800Hz phase continuous, and the frequency transitions occur at the zero crossing point. The transmitter and receiver will work independently, thus providing full-duplex.
