Description

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 Sub-system) 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.

The MX803A is a full-duplex device for use with Single Tone or Selective Call systems. The MX803A consists of a tone decoder with a programmable NOTONE timer, two individual tone encoders and a programmable TX period timer, and an on-chip summing amplifier. Under the control of a C, the MX803A will simultaneously encode and transmit 1 or 2 audio tones in the 208-3000Hz range, as well as detect, decode, and indicate the frequency of any non-predicted input tone in the frequency range of 313 to 6000Hz.

The MX803A is available in 24-pin PDIP (MX803AP), 24-pin PLCC (MX803ALH), and 24-pin SOIC (MX803ADW) packages.
