Example 15— Intel® Stratix® 10 MX (E-Tile)
Power Pin Name | Regulator Group | Voltage Level (V) | Supply Tolerance | Power Source | Regulator Sharing | Notes |
---|---|---|---|---|---|---|
VCC | 1 | 0.85 |
± 30mV | Switcher (*) | Share | Source VCC and VCCP from the same regulator, sharing the same voltage plane. When implementing a filtered supply topology, you must consider the IR drop across the filter. |
VCCP | ||||||
VCCERAM | 2 | 0.9 | ± 30mV | Switcher (*) | Share | Connect the VCCERAM to a dedicated 0.9V power supply. You have the option to connect VCCPLLDIG_SDM to the same regulator as the VCCERAM power plane with proper isolation filtering. When implementing a filtered supply topology, you must consider the IR drop across the filter. |
VCCPLLDIG_SDM | Ferrite Bead Filter | |||||
VCCRT_GXE | LC Filter | Connect VCCRT_GXE to a dedicated 0.9V power supply. You may source VCCRT_GXE from VCCERAM through an LC filter. You may also source VCCRTPLL_GXE from the same regulator as VCCRT_GXE through a ferrite bead. When implementing a filtered supply topology, you must considered the IR drop across the filter. |

VCCRTPLL_GXE | Ferrite Bead Filter | |||||
VCCR_GXB[L,R] | 3 | 1.03 | ± 30mV | Switcher (*) | Share | You have the option to source the VCCR_GXB and VCCT_GXB from the same regulator when all the power rails require the same voltage level. 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 Intel® Stratix® 10 Device Datasheet. |
VCCT_GXB[L,R] | ||||||
VCCPT | 4 | 1.8 | ± 5% (**) | Switcher (*) | Share if 1.8V | You may source VCCPT and VCCBAT from the same regulator. You may connect the VCCH_GXB, VCCA_PLL, VCCPLL_SDM, 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 Intel® Stratix® 10 devices. When implementing a filtered supply topology, you must consider the IR drop across the filter. |
VCCBAT | Varies | |||||
VCCH_GXB[L,R] | 1.8 | Ferrite Bead Filter | ||||
VCCA_PLL | 1.8 | |||||
VCCPLL_SDM | 1.8 | |||||
VCCADC | 1.8 | |||||
VCCH_GXE | 5 | 1.1 | ± 5% (**) | Switcher (*) | Isolate | Connect the VCCH_GXE to a dedicated 1.1V power supply. |
VCCM_WORD_(BL,TL) | 6 | 2.5 | ± 100mV | Switcher (*) | Isolate | Connect VCCM_WORD_(BL,TL) to a 2.5V power supply. |
VCCCLK_GXE | Ferrite Bead Filter | Connect VCCCLK_GXE to a dedicated 2.5V power supply. You have the option to share VCCCLK_GXE with VCCM_WORD if the VRM tolerance is ±100mV or better. When sharing, filter the VCCCLK_GXE with a ferrite bead. |
||||
VCCIO_UIB_(BL,TL) | 7 | 1.2 | ± 30mV | Switcher (*) | Isolate | Connect VCCIO_UIB_(BL,TL) to a 1.2V power supply. |
VCCIO_SDM | 8 | 1.8 | ± 30mV | Switcher (*) | Share if 1.8V | You may source VCCIO, VCCIO_SDM, and VCCIO3V from the same regulator if they are at the same 1.8V voltage level. |
VCCIO | Varies | |||||
VCCIO3V | ||||||
VCCFUSEWR_SDM | 9 | 2.4 | ± 50mV | Switcher (*) | Isolate | Connect VCCFUSEWR_SDM to a dedicated 2.4V power supply if the SDM fuses need to be written. Leave VCCFUSEWR_SDM unconnected or tie it to VCCPT 1.8V power if the SDM fuses do not need to be written. Do not tie this pin to GND. |
(*)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 Intel® Stratix® 10 Core Pins.
(**)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® Stratix® 10 Device Datasheet. Use the EPE (Early Power Estimator) and the Intel® Quartus® Prime Power Analyzer tool to assist in determining the power required for your specific design.
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® Stratix® 10 TX device is provided in the following figure.
