The formula for calculating the Output Frequency (f) is given below:
f = 11.16
* FOUTX *
3.58MHz 3 * I
R
Where FOUTX
= Nominal rated frequency (4Hz, 290Hz or 1160Hz)
FOSC
= Oscillator frequency (2MHz ...... 4MHz)
I
I1
, I
I2
, I
I3
= Input currents for current inputs (16μA at rated)
I
V1
, I
V2
, I
V3
= Input currents for voltage inputs (14μA at rated)
I
R
= Reference current (typically 50μA)
XTAL is a colour burst TV crystal (f = 3.5795 MHz) for the oscillator. The oscillator
frequency is divided down to 1.7897 MHz on-chip, to supply the digital circuitry and the
A/D converters.
