1.8.2. Example 2— Intel® Agilex™ Devices (F-Tile and R-Tile)

Table 36.  Power Supply Sharing Guidelines for Intel® Agilex™ Devices with F-Tile and R-Tile TransceiversExample Requiring 15 Power Regulators
Power Pin Name Regulator Group Voltage Level (V) Supply Tolerance Power Source Regulator Sharing Notes
VCC 1 SmartVID4, 0.8 ± 3% Switcher 5 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 0.8V 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 Intel® Agilex™ 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.

VCCPT 11 1.8 ± 3% 6 Switcher5 Share if 1.8 V

Connect VCCPT to a dedicated 1.8-V power supply.

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 Intel® Agilex™ devices.

If you do not intend to utilize the HPS in the Intel® Agilex™ device, you must still provide power to the HPS power supply pins.

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

VCCIO_HPS
VCCFUSEWR_SDM 15 1.8 ± 50 mV Switcher5 or Linear Isolate A 1.8-V power supply is required on this pin if field-programming of the eFuses is required. If field-programming of the eFuses is not required, tie this pin to VCCPT or leave it unconnected (floating). Do not tie this pin to GND. If field-programming of the eFuses is required, Intel recommends using an adjustable regulator set to 1.8-V output when programming the eFuses.

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 Intel® Agilex™ device is provided in Figure 2.

Figure 2. Example Power Supply Sharing Guidelines for Intel® Agilex™ Devices with F-Tile and R-Tile TransceiversIf an Intel® Agilex™ device without R-tile is used, you can ignore the R-tile power rails. If an Intel® Agilex™ device without F-tile is used, you can ignore the F-tile power rails.
4 For the SmartVID voltage range, refer to the Intel® Agilex™ Device Data Sheet.
5 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 Intel® Agilex™ Pin Connection Guidelines.
6 The supported tolerance for the VCCIO power supply varies depending on the I/O standards. For more details, refer to the I/O standard specification in the Intel® Agilex™ Device Data Sheet. Use the Intel FPGA Power and Thermal Calculator (Intel FPGA PTC) and the Intel® Quartus® Prime Power Analyzer tool to assist in determining the power required for your specific design.
