Product Summary

The CMX654D4 is a transmit modulator. The CMX654D4 is a low power integrated circuit, designed for the transmission of asynchronous 1200bits/sec data in accordance with ITU, V23 and ETSI specifications. The CMX654D4 incorporates an optional Tx data retiming function. This CMX654D4 may be operated so that only the mark or space tone is produced.
