Example 17— Stratix® 10 TX (–2L and –3X parts)
Power Pin Name | Regulator Group | Voltage Level (V) | Supply Tolerance | Power Source | Regulator Sharing | Notes |
---|---|---|---|---|---|---|
VCC | 1 | 0.85 |
±30 mV | Switcher 33 | 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 | ±30 mV | Switcher33 | Share | Connect the VCCERAM to a dedicated 0.9 V power supply. You have the option to connect VCCL_HPS to the same regulator as VCCERAM when the power rails require the same voltage level. You may connect the VCCPLLDIG_SDM and VCCPLLDIG_HPS power rails to the VCCERAM power plane 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 TX 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. |

VCCRT_GXE | Filter | Connect VCCRT_GXE to VCCERAM through an LC filter. For more information about the LC filter design, refer to the Stratix® 10 Power Management User Guide . |
||||
VCCRTPLL_GXE | Filter | You may source VCCRTPLL_GXE from the same regulator as VCCRT_GXE through a ferrite bead. Filtering may be optional if this voltage rail can meet the noise mask requirement. For more information about the noise mask requirements, refer to the Stratix® 10 Power Management User Guide . |

VCCR_GXB[L,R] | 3 | 1.12 | ±20 mV | Switcher33 | 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 | Switcher33 | 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. |
VCCH_GXE | 5 | 1.1 | ±5% 34 | Switcher33 | Isolate | Connect the VCCH_GXE to a dedicated 1.1 V power supply. |
VCCCLK_GXE | 6 | 2.5 | ±5%34 | Switcher33 | Isolate | Connect VCCCLK_GXE to a dedicated 2.5 V power supply. |
VCCPT | 7 | 1.8 | ±5%34 | Switcher33 | Share if 1.8 V | You may source VCCPT and VCCBAT from the same regulator. You may 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. If you do not intend to utilize the HPS in the Stratix® 10 TX 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. When implementing a filtered supply topology, you must consider the IR drop across the filter. |

VCCIO_SDM | 8 | 1.8 | ±5%34 | Switcher33 | Share if 1.8 V | You may source VCCIO_SDM, VCCIO, VCCIO3V, and VCCIO_HPS from the same regulator if they are at the same 1.8 V voltage level. |

VCCFUSEWR_SDM | 9 | 2.4 | ±50 mV | Switcher33 | 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. |
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 TX device is provided in the following figure.
