Brief Description
The FX365A is a half-duplex Processor controlled CTCSS Encoder and Decoder with integral voice-band filtering. This device which is pin and function compatible with standard FX365 microcircuits is also available in a 24pin plastic Small Outline (S.O.I.C.) [365A DW] SMD package. The FX365A demonstrates improved voiceband noise performance and requires less supply current in the Rx monitoring mode. The FX365A has the capability of encoding and decoding 39 separate sub-audio tones, 38 of which are detailed in the current FX365 Data Sheet, plus an additional tone of 69.3Hz. This Data Sheet, which details the differences between the FX365A and the FX365 microcircuits, should be used with the current FX365 Data Sheet.
