New ContributorGeneration Of VCCRCORE for Agilex FPGA
Hi,
Can we directly use the same supply for VCCRCORE and VCCIO_PIO when we have only 1.2V supplies but some IO banks have non DDR4 io standards. (True Differential Inputs , 1.2V TTL outputs /Inputs).
According to following page :
For VCCRCORE we see the following statement. ` Share with VCCIO_PIO when I/O is 1.2V`
In Intel Agilex Review worksheet we see
`Transceiver core power supply. For use in Intel Agilex production devices only (placed here for migration purposes).
Connect the VCCRCORE to 1.2 V power supply.
You have the option to source VCCRCORE from the same regulator as VCCIO_PIO only when you are using the DDR4 I/O standard with proper isolation filtering.`
Do you have a specification/ example for proper isolation filtering. Can we get any other supply as a reference for filtering circuit?
Hi,
Would recommend you to check various Agilex Devlopment kits available. The installers for each of them provides you with useful documents like schematics, BOM etc.
