Cyclone 10 LP JTAG interface voltage

[_Andrey_]

Hello!

In Cyclone 10 LP FPGA Evaluation Kit Board schematic JTAG interface of Cyclone10LP is power by filtered version of 2.5V supply. Is it nessesary? Can I use not filtered 2.5V for JTAG interface?

Hi,

As per our pin connection guidelines, it is recommended to use a filter if you are sharing a power rail.

You may choose not to use a filter but you need to evaluate the power and signal integrity and do it at your own risk.

Thank You.
