Example 9— Intel® Arria® 10 SX

Table 24.  Power Supply Sharing Guidelines for Intel® Arria® 10 SX with Transceiver Data Rate <= 11.3 Gbps for Chip-to-Chip ApplicationsExample Requiring 2 Power Regulators
Power Pin Name Regulator Group Voltage Level (V) Supply Tolerance Power Source Regulator Sharing Notes
VCC 1 0.95 ± 30mV Switcher (*) Share You have the option to source VCC, VCCP, and VCCERAM from the same regulator as VCCL_HPS when all the power rails require the same voltage level. When sharing the same regulator for VCCERAM, VCCL_HPS, 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.
VCCP
VCCERAM
VCCL_HPS
VCCR_GXB[L,R] Isolate

Option provided to share VCCR_GXB and VCCT_GXB with the same regulator as VCC, VCCP, and VCCERAM when all power rails require 0.95 V with proper isolation filter. For details, refer to note 1 of the Notes to Power Supply Sharing Guidelines. 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.

When implementing a filtered supply topology, you must consider the IR drop across the filter. 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.

VCCT_GXB[L,R]
VCCBAT 2 Varies ± 5% (**) Switcher (*) Share if 1.8V Option provided for VCCBAT, VCCPT, VCCIO, VCCPGM, VCCIO_HPS, and VCCIOREF_HPS 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 Intel® Arria® 10 devices.
VCCPT 1.8
VCCIO Varies
VCCPGM
VCCIO_HPS
VCCIOREF_HPS 1.8
VCCH_GXB[L,R] 1.8 Isolate Option provided to share VCCH_GXB, VCCA_PLL, and VCCPLL_HPS with the same regulator as VCCBAT, VCCPT, VCCIO, VCCPGM, VCCIO_HPS, and VCCIOREF_HPS when all power rails require 1.8 V with a proper isolation filter.
VCCA_PLL
VCCPLL_HPS

(*)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 SX 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 SX device is provided in Figure 9.
