The CMX881 is a full-function half-duplex audio and signalling baseband processor IC designed for both Professional Mobile Radio (PMR) and trunked radio systems. It caters to all voiceband requirements including filtering, pre/de-emphasis, audio routing, and global level setting. The device features an embedded 1200/2400 bps MSK/FFSK freeformat modem with sync detection and MPT standard CRC operations, alongside CTCSS and DCS signalling functions.
