Example 4— Intel® Arria® 10 GT

Table 19.  Power Supply Sharing Guidelines for Intel® Arria® 10 GT with Transceiver Data Rate <= 11.3 Gbps for Chip-to-Chip ApplicationsExample Requiring 3 Power Regulators
Power Pin Name Regulator Group Voltage Level (V) Supply Tolerance Power Source Regulator Sharing Notes
VCC 1 0.9 ± 30mV Switcher (*) Share You have the option to source VCC and VCCP from the same regulator as
when all the power rails require the same voltage level. When sharing the same regulator for VCCERAM, VCC, and VCCP, the SmartVID feature is not available. If you use the SmartVID feature, then VCC and VCCP need to be sourced by a separate dedicated regulator.
VCCR_GXB[L,R] 2 0.95 ± 30mV Switcher (*) Share

VCCR_GXB and VCCT_GXB must be 1.03 V or higher in order to support PCIe Gen 3. To meet DisplayPort TX electrical full compliance, VCCT_GXB must be 1.03 V or higher.

For designs that have high-current for VCCR_GXB or VCCT_GXB, you should consider the IR drop through the supply planes and compensate for it.

VCCBAT 3 Varies ± 5% (**) Switcher (*) Share if 1.8V Option provided for VCCBAT, VCCPT, VCCIO, and VCCPGM to share the same regulator when all power rails require 1.8 V. Depending on the regulator capabilities, you have the option to share this supply with multiple Arria 10 devices.
VCCIO Varies
VCCH_GXB[L,R] 1.8 Isolate Option provided to share VCCH_GXB and VCCA_PLL with the same regulator as VCCBAT, VCCPT, VCCIO, and VCCPGM when all power rails require 1.8V with a proper isolation filter.

(*)When using a switcher to supply these voltages, the switcher must be a low noise switcher as defined in note 7 of the Notes to Intel® Arria® 10 GX and GT Pin Connection Guidelines.

(**)The supported tolerance for the VCCIO power supply varies depending on the I/O standards. For more details, refer to the I/O standard specification in the Intel® Arria® 10 Device Datasheet. Use the EPE (Early Power Estimation) tool to assist in determining the power required for your specific design.

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 Intel® Arria® 10 GT device is provided in Figure 4.
