FX803DW 제품 상세 정보
As part of the DBS 800 System, this audio signalling processor will provide an inband tone signalling facility for PMR radio systems. Signalling systems supported include Selcall (CCIR, ZVEI I, II and III, EEA), 2-Tone Selcall and Dual Tone Multi-Frequency (DTMF) encode.
Using a non-predictive tone decoder and versatile encoders gives the FX803 the capability to work in any standard or non-standard tone system.
This is a full-duplex device consisting of:
● Two individual tone generators and a programmable (Tx) period timer.
● A tone decoder with programmable NOTONE Timer.
● An on-chip summing amplifier.
For use with Single Tone or Selective Call systems.
Under the control of the µController, via “C-BUS,” the FX803 will encode and transmit a single or pair of audio tones, in the frequency range 208Hz to 3kHz, simultaneously, and detect, decode and indicate the frequency of non-predicted input tones in the frequency range 313Hz to 6kHz.
Both tone generators can be individually placed into a power economical “Powersave” mode.
A general purpose logic input, interfacing directly with the Status Register, is provided. This could be used as an auxiliary method of routeing digital information to the µController via the “C-BUS.”
The output frequencies are produced from data loaded to the device, with a programmable, general purpose, on-chip timer available to indicate the tone transmit periods.
A Dual Tone Multi-Frequency (DTMF) output is obtained by combining the 2 independent output frequencies in the integral summing amplifier. This Summing Amplifier output is also available for level adjustment.
Tones produced by the FX803 can also be used in the DBS 800 system as modulation calibration inputs and for “CUE” audio indications for the operator.
Received tones are measured and their frequency indicated to the µController in the form of a received data word. A poor-quality or incoherent tone will, after a programmed period, indicate NOTONE.
The FX803 is a low-power, 5-volt CMOS integrated circuit and is available in 24-pin DIL cerdip and 24-pin/lead plastic SMD packages.
