CTCSS/DCS/SELCALL Processor  
FX828  
1.5  
General Description  
The FX828 is a signalling encoder/decoder for use in land mobile radio equipment, see Figure 1. The  
transmitter section of this device has independently controllable tone generators for sub-audio  
(CTCSS) and inband (Selcall) signalling. It also features a DCS code generator, which may be used in  
place of the CTCSS tone generator.  
The receiver section of the FX828 has a fast/predictive CTCSS tone detector which operates in parallel  
with a DCS decoder and a CTCSS/Selcall tone decoder. The latter is switchable to perform either  
CTCSS or Selcall tone decoding of a user-programmable set of up to 15 tones. In the CTCSS mode it  
performs a more accurate (but slower) analysis of the tones detected by the fast/predictive CTCSS  
tone detector, which is a single detector that is switchable to provide either a fast response to any  
CTCSS tone (FAST DETECT mode) or a fast response to a single user-programmed CTCSS tone  
(PREDICTIVE mode).  
Other functions on the FX828 are a comparator with programmable threshold level, a general purpose  
timer and a summing amplifier with two adjustable gain blocks, which may be used for two point  
modulation, for example. All FX828 functions are controlled by an external µC over the C-BUS  
interface, a serial interface designed to reduce interference levels in radio equipment.  
1.5.1 Software Description  
Address/Commands  
Instructions and data are transferred, via "C-BUS", in accordance with the timing information given in  
Figure 4.  
Instruction and data transactions to and from the FX828 consist of an Address/Command (A/C) byte  
followed by either:  
(i)  
(ii)  
a further instruction or data (1 or 2 bytes) or  
a status or Rx data reply (1 byte)
