Newbie here.
I'm ordering a rls brand magnetic encoder.
In the selection criteria it asks what hz do you want.
Ranging from 1mhz-15mhz.
I was going to select 15mhz but unsure if there will be a issue.

Part number is
Rlc2hda2d0k00c00.
1micro meter resolution.
Also going to use a ua9639 line receiver.
