New ContributorCyclone 10 LP JTAG interface voltage
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.
