Product Summary

The CMX605D4 is an integrated telecom tone generator and DTMF encoder/decoder, which is designed for ISDN interfaces, Wireless Local Loop and Analogue to Digital Phone Conversion systems. The tone generator covers an extensive range of pre-programmed tones used in analogue phone systems (POTS). Three outputs of CMX605D4 are provided: ‘Ringing signals’, ‘In-band tones or FSK data’, and ‘12kHz/16kHz Metering pulses’. Simple software control facilitates the interface to a wide range of commonly used μCs and SLICs, enabling a comprehensive analogue telephone line presentation. The applications of the CMX605D4 include Digital Line to POTS Interface, Subscriber Terminal Adapters, Computer Telephony Integration, Telephone/Radio Patch Systems, Pair Gain Systems, Billing/SPM Systems.
