The formula for calculating the output frequency (f) is given below:

f = 11.16 * FOUTX *

FOSC

*

I

3.58MHz

I

R

2

Where FOUTX

= Nominall rated frequency (4Hz or 1160Hz)

FOSC

= Oscillator frequency (2MHz ...... 4MHz)

I

I

= Input currents for current input (16µA at rated)

I

V

= Input current for voltage input (14µA at rated)

I

R

= Reference current (typically 50µA)

XTAL is a colour burst TV crystal (f = 3.5795MHz) for the oscillator. The oscillator

frequency is divided down to 1.7897MHz on-chip to supply the digital circuitry and the

A/D converters.
