Table 15.   Agilex™ 7 E-Tile Decoupling Capacitors Summary per Tile
Agilex™ 7 PTC Rail Name Bottom-side Capacitors FPGA Periphery Capacitors Notes
Thick PCB (≥65 mil thickness) Thin PCB (≤65 mil thickness) Thick PCB (≥65 mil thickness) Thin PCB (≤65 mil thickness)
VCCRT_GXE 6x 4.7uF 0201 6x 4.7uF 0201 LC filter capacitors LC filter capacitors

Per each E-Tile.

This is applicable to both reasonable worst case and low power scenario case. For the low power scenario case, the maximum current is 3 A, and the difference is the LC filter capacitors.

For more information, refer to the Connection Requirement and Filter Recommendation for VCCRT_GXE per Tile and Connection Requirement and Filter Recommendation for VCCRT_GXE per Tile (Low Power Scenario) figures.

VCCRTPLL_GXE 2x 1uF 0201 2x 1uF 0201 LC filter capacitors LC filter capacitors Per each E-Tile
VCC_HSSI_GXE

3x 10uF 0402 or 10x 4.7uF 0201

3x 10uF 0402 or 10x 4.7uF 0201

 N/A N/A Per each E-Tile
VCCH_GXE 2x 4.7uF 0201 2x 4.7uF 0201 1x 22uF 0603 1x 22uF 0603 Per each E-Tile
VCCCLK_GXE 1x 1uF 0201 1x 1uF 0201 N/A N/A Per each E-Tile

Although it is not required to use the recommended decoupling capacitors and LC filters for unused E-Tile, Altera recommends you to use at least one of each suggested decoupling capacitors for the bottom-side capacitors if the E-Tile is not used.

If you plan to run the E-Tile based on OTN protocol standards, contact Intel® Premier Support and quote ID #1509475736 to receive a step-by-step guideline about updating or adjusting the PCB decoupling capacitors for E-Tile (only for VCCRT_GXE and VCCRTPLL_GXE power rails) to support the OTN application.
