Table 11.  Power Supply Sharing Guidelines for Intel® Cyclone® 10 GX 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 ±30 mV Switcher (*) Share —
VCCP
VCCERAM
VCCR_GXBL 2 0.95 ±30 mV Switcher (*) Share

For better performance, isolate VCCR_GXB and VCCT_GXB from each other.

To meet DisplayPort TX electrical full compliance, VCCT_GXB must be 1.03V.

VCCT_GXBL
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 required 1.8V. Depending on the regulator capabilities, you have the option to share this supply with multiple Intel® Cyclone® 10 GX devices.
VCCPT 1.8
VCCIO Varies
VCCPGM
VCCH_GXBL 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.
VCCA_PLL

(*)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® Cyclone® 10 GX 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® Cyclone® 10 GX 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® Cyclone® 10 GX device is provided in Figure 1.
