  • Brief Description

    CMX881, a full-function half-duplex audio and signalling processor IC for both PMR and Trunked radio systems suitable for complex and simple end-designs. Under the control of the host µC, all voiceband requirements are catered for: voiceband and sub-audio filtering, pre/de-emphasis and audio routing and global level setting with single or two-point modulation in the transmit path.


    • Automatic signal type scanning and IRQ on detection of valid Rx signals, level or RSSI
    • Tone generator for caller recognition tunes
    • Programmable powerdown control
    • Programmable signal detection thresholds
    • Low Power operation with ‘Zero Power’ mode
    • Uncommitted Aux ADC with switchable input to monitor signals
    • Meets ETS 300 086, MPT1327, PAA1382 and ETS 300 230 specifications
    • Voice processing facilities, including Tx and Rx gain setting and voice/subaudio filtering
    • C-BUS serial host interface
    • RF interface allowing 1 or 2 point modulation
    • Programmable soft limiter
    • Enhanced CTCSS and 23/24 bit DCS codecs
    • Zero ‘Talkdown’ CTCSS decoder performance prevents dropouts
    • DTMF transmitter
    • Programmable Selcall codec
    • Robust half-duplex FFSK/MSK modem, 1200/2400bps with CRC and parity generator/checker, gets data through when signal is too degraded for voice – for text messaging/paging, location transfer, etc. applications.
