Hello,
I am looking for an IC that can read the output frequency of an oscillator range 0.15Mhz-3Mhz with 18.75kHz accuracy over i2c or SPI. I am using this chip to automate the oscillator frequency. Any ideas?
Thanks in advance!

A simple MCU would probably be the best option. $1 MCU would do the trick, but would require some programming, of course.

For an example of how to measure frequency with a microcontroller, just search for "arduino frequency counter", e.g.:
