Table 30.  Power Supply Sharing Guidelines for Agilex™ 7 M-Series Devices with R-Tile, F-Tile Transceivers, and HBM2E, Using DDR4Example Requiring 9 Power Regulators
Power Pin Name Regulator Group Voltage Level (V) Supply Tolerance Power Source Regulator Sharing Notes
VCC 1 SmartVID1, 0.8 ±3% Switcher 2 Share

Source VCC and VCCP from the same regulator, sharing the same voltage plane. You have the option to connect VCCL_HPS to the same regulator as VCC and VCCP when the power rails require the same voltage level. You may also connect the VCCPLLDIG_HPS power to the shared VCC, VCCP, and VCCL_HPS power planes with proper isolation filtering.

For -4X devices, VCC and VCCP are powered by SmartVID and a separate fixed 0.8 V supply must be used for VCCL_HPS and filtered VCCPLLDIG_HPS.

When implementing a filtered supply topology, you must consider the IR drop across the filter.

If you do not intend to utilize the HPS in the Agilex™ 7 M-Series device, you must still provide power to these power supply pins. Do not leave the VCCL_HPS and VCCPLLDIG_HPS power supply pins floating or connected to GND.

Each board design requires its own power analysis to determine the required power regulators needed to satisfy the specific board design requirements. An example block diagram using the Agilex™ 7 M-Series devices is provided in the following figure.

1 For the SmartVID voltage range, refer to the Agilex™ 7 FPGAs and SoCs Device Data Sheet: M-Series .
2 When using a switcher to supply these voltages, the switcher must be a low noise switcher as defined in note 4 of the Notes to Agilex™ 7 M-Series Device Family Pin Connection Guidelines .
3 You may supply the VCCIO_PIO voltage rail of a sub-bank with a ±5% voltage tolerance only if the entire sub-bank is operating in any of the LVDS SERDES receiver mode with the use of 1.05 V, 1.1 V, or 1.2 V True Differential Signaling input standard, PHY Lite mode, or GPIO mode. Otherwise, you must supply the VCCIO_PIO voltage rail with a ±3% voltage supply tolerance.
