CMX813E4 Datasheet PDF - MX-COM Inc

The CMX813 decodes the signaling tones for the Motorola Quick Call series, GE groups A, B and C and the tonesets employed by the Zetron, Reach and Plectron 2-tone radio paging systems. It also decodes the tones for Motorola 5/6-tone paging and the EIA, CCIR, ZVEI1 and EEA tonesets used for HSC radio paging and SELCALL. A simple serial interface allows the host µC to specify the individual tone(s), or group of tones, to be decoded from the extensive list held by the CMX813.
