display the frequency by a dsp processor

in my project I have to read the output frequency of an oscillator (150 Mhz) with a microcontroller (here arduino), the maximum frequency of microcontroller is 16 MHz, so I have to use a frequency divider, someone can suggest me what type of divider can tolerate> 150 mhz?

Have a google for pre-scalers.. There are plenty available from the usual supplers.

A suitable one is the SP8630. This seems to be divide-by-ten at up to 600MHz. It is ECL, so you have a little interfacing to do.

Another device is the MC12080. Again this seems to be ECL.

Here is a good introduction to ECL: https://global.oup.com/us/companion.websites/fdscontent/uscompanion/us/static/companion.websites/9780199339136/pdf/Additional_Material.pdf
