Brief Description  
The Rx sub-audio (CTCSS) path contains a  
The FX365C is a 3-volt, half-duplex predictive  
Continuous Tone Controlled Squelch System  
(CTCSS) encoder/decoder microcircuit. The FX365C  
has integral voice-band filtering for prefiltering of Tx  
audio and the rejection of the CTCSS tone in receive.  
Under µProcessor control, the FX365C will encode  
and decode any one of 39 sub-audio frequencies  
(+NOTONE) in the range 67.0Hz to 250.3Hz. Tone  
frequencies and all functional commands can be  
loaded to the device in either pin-selectable 8-bit  
parallel or serial format.  
(selected tone frequency) bandpass filter and period  
detector providing a logic level output (Rx Tone  
Detect) to indicate a successful decode operation.  
Rx “Press to Listen” (PTL) and Tx “Squelch-Tail  
Elimination” functions are available in both command  
loading modes. The squelch-tail elimination function  
will provide (Tx tone) phase-reversal to minimise the  
annoying audio outputs that occur at the receiver on  
completion of a transmission.  
Tone frequencies and filter accuracies are  
maintained by an on-chip 1.0MHz clock oscillator  
employing an external crystal or clock pulse input.  
The FX365C, which exhibits high audio and sub-  
audio performance with low falsing, is available in 24-  
pin DIL and small outline SMD packages.  
A separate, Rx/Tx voice-audio path is available with  
a highpass (sub-audio reject) filter automatically  
placed in the relevant Rx or Tx voice line.
