MX803AJ Datasheet PDF - MX-COM Inc

The MX803A is an audio signaling processor that provides inband tone signaling capabilities for LMR and other Radio systems. A low-power CMOS device, the MX803A is a member of the DBS800 (Digitally integrated Baseband Subsystem) IC family (See section 4.2). Supported Signaling systems include SelCall (CCIR, EEA, ZVEI I, II, and III) 2-Tone SelCall and DTMF encode. The use of a non-predictive decoder and a versatile encoder, allows the MX803A to operate in any standard or non-standard tone system.
