Table 45.  Power Supply Sharing Guidelines for Stratix® 10 SX (–1V, –2V, and –3V parts) (only for the HF35 Package) with 15 Gbps < Transceiver Data Rate <= 28.3 GbpsExample Requiring 8 Power Regulators
Power Pin Name Regulator Group Voltage Level (V) Supply Tolerance Power Source Regulator Sharing Notes
VCC 1

SmartVID

±30 mV Switcher 21 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 Stratix® 10 SX device, you must still provide power to the HPS power supply. Do not leave the VCCL_HPS and VCCPLLDIG_HPS floating or connect them to GND.

VCCERAM 2 0.9 ±30 mV Switcher21 Isolate

Connect the VCCERAM to a dedicated 0.9 V power supply. You may connect the VCCPLLDIG_SDM power to the VCCERAM power plane with proper isolation filtering.

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

VCCR_GXB[L,R] 3 1.12 ±20 mV Switcher21 Isolate

Connect the VCCR_GXB to a dedicated 1.12 V power supply.

The VCCR_GXB and VCCT_GXB voltage supplies can vary depending on whether it is an L-Tile or H-Tile device as well as the channel configuration (non-bonded versus bonded channels) on each tile. For more information about the voltage requirement for your specific use case, refer to the Stratix® 10 Device Datasheet.

VCCT_GXB[L,R] 4 1.12 ±20 mV Switcher21 Isolate

Connect the VCCT_GXB to a dedicated 1.12 V power supply.

The VCCR_GXB and VCCT_GXB voltage supplies can vary depending on whether it is an L-Tile or H-Tile device as well as the channel configuration (non-bonded versus bonded channels) on each tile. For more information about the voltage requirement for your specific use case, refer to the Stratix® 10 Device Datasheet.

VCCPT 5 1.8 ±5% 22 Switcher21 Share if 1.8 V

You may source VCCPT and VCCIO_SDM from the same regulator. You may connect the VCCIO, VCCIO3V, VCCIO_HPS, and VCCBAT to the same power plane if the those power rails are at the same voltage level. You may also connect the VCCH_GXB, VCCA_PLL, VCCPLL_SDM, VCCPLL_HPS, and VCCADC to the same power plane with proper isolation filtering. Depending on the regulator capabilities, you have the option to share this supply with multiple Stratix® 10 devices.

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 Stratix® 10 SX device, you must still provide power to the HPS power supply. Do not leave the VCCIO_HPS and VCCPLL_HPS floating or connect them to GND.

VCCIO3D 6 1.8 ±5%22 Switcher21 Isolate Connect VCCIO3D to a 1.8 V power supply.
VCCFUSEWR_SDM 7 2.4 ±50 mV Switcher21 Isolate Connect VCCFUSEWR_SDM to a dedicated 2.4 V power supply if the SDM fuses need to be written. Leave VCCFUSEWR_SDM unconnected or tie it to VCCPT 1.8 V power if the SDM fuses do not need to be written. Do not tie this pin to GND.
VCCIO3C 8 3.0V/3.3V ±5%22 Switcher21 Isolate

Connect VCCIO3C to a 3.0 V or 3.3 V power supply.

Only 1SG040 (HF35 package), 1SX040 (HF35 package), and 1ST040 (HF35 package) support 3.3 V VCCIO3C.

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 Stratix® 10 SX device is provided in the following figure.

21 When using a switcher to supply these voltages, the switcher must be a low noise switcher as defined as defined in note 7 of the Notes to Stratix® 10 Core Pins.
22 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 Stratix® 10 Device Datasheet. Use the EPE (Early Power Estimator) or Power and Thermal Calculator (PTC), and the Quartus® Prime Power Analyzer tool to assist in determining the power required for your specific design.
