EVAL-AD9557 for generating clock signal that matches varying input frequency?

Greetings!

To provide some contextual background, I'm looking for a solution to generate clock multiples of the fs laser pulse rate, which can be something close to 80  MHz, in my case 80.11 MHz. During laser operation this frequency constantly changes by less than 100 ppm at the rate of ~ 15 Hz. I was recommended AD9557 for the job

AD9523-1  Can I precisely adjust output clock frequency with AD9523-1 (EVAL-AD9523-1)? 

 

I just would like to follow up and confirm if AD9557 is going to "follow" this small frequency drift with this configuration?

 

Thank you!

Dmitri
