1.4.1. P-Tile Power Supply Pins

Note: Altera recommends that you create a Quartus® Prime design, enter your device I/O assignments, and compile the design. The Quartus® Prime software checks your pin connections according to I/O assignment and placement rules. The rules differ from one device to another based on device density, package, I/O assignments, voltage assignments, and other factors that are not fully described in this document or the device user guides.
Table 16.  P-Tile Power Supply Pins
Pin Name Pin Functions Pin Description Connection Guidelines
VCCH_GXP[L1,L3] Power

Secondary high-voltage analog supply for transceivers, and on-die PLL specific to P-Tile.

For more information about the supported pins, refer to the device pin-out file.

Connect VCCH_GXP to a 1.8-V low noise switching regulator. This voltage rail can be shared with VCCPT using proper isolation filtering.

VCCH_GXP must be powered up even when the P-Tile transceivers are not used. For more details about the decoupling recommendations for this voltage rail, refer to the Agilex™ 7 Power Distribution Network Design Guidelines .

VCCRT_GXP[L1,L3] Power

Primary analog supply for the TX and RX channels, specific to P-Tile.

For more information about the supported pins, refer to the device pin-out file.

Connect VCCRT_GXP to a 0.9-V low noise switching regulator. This voltage rail can be shared with VCCH using proper isolation filtering.

VCCRT_GXP must be powered up even when the P transceivers are not used. For more details about the decoupling recommendations for this voltage rail, refer to the Agilex™ 7 Power Distribution Network Design Guidelines .

VCCCLK_GXP[L1,L3] Power

LVCMOS I/O buffer supply rail, specific to P-Tile.

For more information about the supported pins, refer to the device pin-out file.

Connect VCCCLK_GXP to a 1.8V low noise switching regulator. This voltage rail can be shared with VCCPT using proper isolation filtering.

VCCCLK_GXP must be powered up even when the P-Tile transceivers are not used. For more details about the decoupling recommendations for this voltage rail, refer to the Agilex™ 7 Power Distribution Network Design Guidelines .

VCCFUSE_GXP Power

Required power supply for the firmware to read internal settings for the one-time programmable eFuses.

Connect this voltage rail to a 0.9-V power supply. This rail must be shared with VCC_HSSI_GXP.

VCCFUSE_GXP must be powered up even when the P-Tile transceivers are not used. For more details about the decoupling recommendations for this voltage rail, refer to the Agilex™ 7 Power Distribution Network Design Guidelines .

VCC_HSSI_GXP[L1,L3] Power

Primary digital supply for all digital signals, specific to P-Tile.

For more information about the supported pins, refer to the device pin-out file.

Connect VCC_HSSI_GXP to a 0.9-V low noise switching regulator. This voltage rail must be shared with VCCH.

VCC_HSSI_GXP must be powered up even when the P-Tile transceivers are not used.
