1.8.2. Example 2— Agilex™ 7 Devices (F-Tile and R-Tile)
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 0.8 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 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 | 8 | 1.8 | ± 3% | 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 Agilex™ 7 devices. If you do not intend to utilize the HPS in the Agilex™ 7 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. |

VCCFUSEWR_SDM | Share | A 1.8-V power supply is required on this pin if the field-programming of the eFuses is required. In addition, Altera recommends connecting a regulator with 1.8-V output to allow access to enhanced configuration and security debug tools. If you choose not to power this pin, tie this pin to VCCIO_SDM or leave it unconnected (floating). Do not tie this pin 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 device is provided in the Example Power Supply Sharing Guidelines for Agilex™ 7 Devices with F-Tile and R-Tile Transceivers figure.
