1.3.1. GTS Transceiver 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.

VCC_HSSI_L1

VCC_HSSI_R4

Power

GTS transceiver digital logic power supply.

  • For the devices with speed grade –1V, –2V, –2E, –3V, and –4S, it is 0.8-V.
  • For the devices with speed grade –5S, it is 0.78-V.
  • For the devices with speed grade –6S and –6X, it is 0.75-V.

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

Connect VCC_HSSI to low noise switching regulator. Refer to Power Distribution Network Design Guidelines: Agilex™ 5 FPGAs and SoCs for the decoupling capacitor requirement.

Do not tie it to GND or leave it floating if unused.

VCCEHT_GTS[L1,R4][A,B,C,D] Power

GTS transceiver high-voltage analog power supply pins.

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

VCCEHT_GTS should share 1.8-V rail with VCCPT through a proper isolation filtering. Refer to Power Distribution Network Design Guidelines: Agilex™ 5 FPGAs and SoCs for fitter details and decoupling capacitor requirement.

Tie to GND if the GTS transceiver bank supports power down and you do not plan to use it in the future. Refer to GTS Transceiver PHY User Guide for GTS transceiver bank that supports power down.

VCCERT_GTS[L1,R4][A,B,C,D] Power

GTS transceiver analog 1.0-V logic power pins.

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

Connect VCCERT_GTS to 1.0-V dedicated regulator. Refer to Power Distribution Network Design Guidelines: Agilex™ 5 FPGAs and SoCs for decoupling capacitor requirement.

Tie to GND if the GTS transceiver bank supports power down and you do not plan to use it in the future. Refer to GTS Transceiver PHY User Guide for GTS transceiver bank that supports power down.
