Table 32.  Power Supply Sharing Guidelines for Agilex™ 5 Devices with Speed Grade -1V, -2V, -2E, and -3VExample Requiring 6 Power Regulators
Power Pin Name Regulator Group Voltage Level (V) Supply Tolerance Power Source Regulator Sharing Notes
VCC 1 SmartVID 1, 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.

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™ 5 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.

VCCL_SDM 2 0.8 ±3% Switcher2 Share Connect the VCCL_SDM to a dedicated 0.8-V power supply. When implementing a filtered supply topology, you must consider the IR drop across the filter.
VCC_HSSI
VCCPLLDIG_SDM Filter
VCCERT_GTS 3 1.0 ±2.5% Switcher2 or Linear Share

Connect to a dedicated 1.0-V power supply.

For no transceiver device, move VCCH_SDM together with VCCL_SDM.

VCCH_SDM
VCCPT 4 1.8 ±2.5% Switcher2 Share

Connect VCCPT to a dedicated 1.8-V power supply.

Connect VCCADC, VCCPLL_SDM, VCCPLL1_HPS, VCCPLL2_HPS, and VCCCEHT_GTS 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™ 5 devices.

VCCRCORE 5 1.2 ±5% or ±3% 3 Switcher2 Share

Connect to a dedicated 1.2-V power supply. If you have LVDS Tx signals on the sub-bank of your board, the VCCIO_PIO of this sub-bank is 1.3-V. In this case, you need another VR to support this sub-bank.

VCCIO_HVIO 6 3.3/2.5/1.8 ±3% Switcher2 Isolate Connect to a dedicated 3.3-V, 2.5-V, or 1.8-V power supply.

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™ 5 devices is provided in the following figure.

1 For the SmartVID voltage range, refer to the Agilex™ 5 FPGAs and SoCs Device Data Sheet.
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™ 5 Pin Connection Guidelines .
3 Refer to the Agilex™ 5 FPGAs and SoCs Device Data Sheet for VCCIO_PIO use cases, to decide the voltage tolerance is ± 3% or ± 5%.
