Increase KCU 105 Line Rate Limit

Hey,

we are working with a KCU105 board and are trying to set the max line rate up to 16 GHz. We already modified the GUI accordingly and are now wondering what else we have to change.

Does anybody have an idea?

Thanks,

Felix

Re: Increase KCU 105 Line Rate Limit

Hello @icrelated,

In addition, to the line rate, you need to check the reference clock rate. This allows the wizard to set the necessary MGT parameters to meet the data sheet specifications and will lock the MGT into a narrow line rate range.

Notes:
1. Tested at most commonly used line rate of 6250 Mb/s using 390.625 MHz reference clock.
2. Tested at a line rate of 9950 Mb/s using 155.46875 MHz reference clock and 11100 Mb/s using 173.4375 MHz reference
clock.

Regards,

Naveen
