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)
