Brief Description

The FX613 is a wide-band, ‘N-Tone’, non-predictive

Current frequency information is output for the

µProcessor using a Serial Data, Clock and Interrupt

interface.

tone decoder to measure telephone system call progress

tones in PABX, Pay/Feature-Phone, Fax and Modem

systems.

Adhering to Must/Must-Not Decode limits and able to

measure inband frequencies in outband modulation, this

decoder measures the frequency of input signals in the

range 300Hz to 2,150Hz; the result of each

measurement is presented to a system µProcessor, as a

6-bit serial word.

The decode frequency range, which covers the

World's call progress application spectrum, is processed

internally as two bands: LO = 300Hz to 660Hz and HI =

900Hz to 2150Hz. Frequency measurement is achieved

by counting the number of cycles in a set time period

(LO = 39.47ms or HI = 13.16ms). Bad signal/level quality

or N^OTONEresults in a count-abort, timing-reset and no

output from the decoder.

Data from the FX613 should be processed by a

µProcessor whose algorithms are able to recognize the

frequency, sequence and/or cadence of input signals as

national call progress information; e.g.: ‘Dial’, ‘Busy’,

‘Number-Unobtainable’, ‘Ringing’ and automatic tones

employed by Fax, Modem systems. Software can be

simply configured to reject speech frequencies.

Due to its ‘N-Tone’, non-predictive decoding capability,

units employing the FX613 can be redeployed under a

new national standard by a simple software amendment.

Available in 16-pin plastic S.O.I.C. SMD and 14-pin

plastic DIL packages, this low-cost, mixed analogue/digital

microcircuit has a typical power requirement of less than

1mA at 3 volts and utilizes a telecom-system clock input

of 3.579545MHz to maintain frequency accuracy.
