1.7.18. Example 18— Stratix® 10 DX (–1V, –2V, and –3V parts)
| Power Pin Name | Regulator Group | Voltage Level (V) | Supply Tolerance | Power Source | Regulator Sharing | Notes |
|---|---|---|---|---|---|---|
| VCC | 1 | SmartVID | ±30 mV | Switcher 35 | 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 DX 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 | Switcher35 | Share | Connect VCCERAM and VCCFUSE_GXP to a dedicated 0.9 V power supply. You may connect the VCCPLLDIG_SDM and VCCRT_GXP power to the shared VCCERAM and VCCFUSE_GXP power planes with proper isolation filtering.

| VCCRT_GXE | LC Filter | Connect the VCCRT_GXE to a dedicated 0.9 V 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 consider the IR drop across the filter. |

| VCCPT | 4 | 1.8 | ±5%36 | Switcher35 | Share if 1.8 V | You can source VCCPT and VCCBAT from the same regulator, sharing the same voltage plane. You have the option to connect VCCA_PLL, VCCPLL_SDM, VCCPLL_HPS, VCCADC, and VCCCLK_GXP to the same power plane with proper isolation filtering. If you do not intend to utilize the HPS in the Stratix® 10 DX device, you must still provide power to the HPS power supply. Do not leave the VCCPLL_HPS floating or connect them to GND.
