1.7.6. Example 6— Agilex™ 7 M-Series Devices with F-Tile only and Without HBM2E Using DDR5

Table 35.  Power Supply Sharing Guidelines for Agilex™ 7 M-Series Devices with F-Tile Transceivers only, Without HBM2E Using DDR5Example Requiring 9 Power Regulators
Power Pin Name Regulator Group Voltage Level (V) Supply Tolerance Power Source Regulator Sharing Notes
VCC 1 SmartVID15, 0.8 ±3% Switcher 16 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.

Connect VCCADC, VCCPLL_SDM, VCCPLL_HPS, VCCH_FGT_GXF, and VCCCLK_GXF to the same power plane with proper isolation filtering.

Depending on the regulator capabilities, you have the option to share this supply with multiple Agilex™ 7 M-Series devices.

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.

15 For the SmartVID voltage range, refer to the Agilex™ 7 FPGAs and SoCs Device Data Sheet: M-Series .
16 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 .
