1.5.1. Stratix® 10 P-Tile Power Supply Pins
Pin Name | Pin Functions | Pin Description | Connection Guidelines |
---|---|---|---|
VCCH_GXP[L, R][1, 2, 3] | Power | Secondary high-voltage analog supply for transceivers and on-die PLL specific to P-Tile. | Connect VCCH_GXP to a 1.8 V low-noise switching regulator. Place a 22–nF decoupling capacitor between each VCCH_GXP power pin and GND pin on the back side of the BGA pin field. VCCH_GXP must be filtered through the ferrite bead. VCCH_GXP must be powered up even when the P-Tile transceivers are not used. |
VCCRT_GXP[L, R][1, 2, 3] | Power | Primary analog supply for the TX and RX channels, specific to P-Tile. | Connect VCCRT_GXP to a 0.9 V low-noise switching regulator. With a proper isolation filtering, you have the option to source VCCRT_GXP from the same regulator as VCCERAM. VCCRT_GXP must be powered up even when the P-Tile transceivers are not used. |
VCCCLK_GXP[L, R][1, 2, 3] | Power | LVCMOS I/O buffer supply rail, specific to P-Tile. | Connect VCCCLK_GXP to a 1.8 V low-noise switching regulator. With a proper isolation filtering, you have the option to source VCCCLK_GXP from the same regulator as VCCPT. VCCCLK_GXP must be powered up even when the P-Tile transceivers are not used. |
VCCFUSE_GXP | Power | Required power supply for the firmware to read internal settings for the one-time programmable eFuses. | Connect the VCCFUSE_GXP pin to the 0.9 V VCCERAM power. Connecting to the VCCERAM power rail adheres to the power-down sequencing requirement for the VCCFUSE_GXP supply. Do not leave this pin floating or tie it to GND. VCCFUSE_GXP must be powered up even when the P-Tile transceivers are not used. |
