VCCA_GXB
VCCH_GXB
Unit
If BOTH of the following conditions are true:
1.05
• Data rate > 10.3 Gbps.
• DFE is used.
If ANY of the following conditions are true (122)
:
1.0
3.0
2.5
• ATX PLL is used.
• Data rate > 6.5Gbps.
1.5
V
• DFE (data rate ≤ 10.3 Gbps), AEQ, or EyeQ
feature is used.
If ALL of the following conditions are true:
0.85
• ATX PLL is not used.
• Data rate ≤ 6.5Gbps.
• DFE, AEQ, and EyeQ are not used.
DC Characteristics
Supply Current
Standby current is the current drawn from the respective power rails used for power budgeting.
Use the Excel-based Early Power Estimator (EPE) to get supply current estimates for your design because these currents vary greatly with the
resources you use.

If the VCCR_GXB and VCCT_GXB supplies are set to 1.0 V or 1.05 V, they cannot be shared with the VCC core supply. If the VCCR_GXB and
VCCT_GXB are set to 0.85 V, they can be shared with the VCC core supply.
Choose this power supply voltage requirement option if you plan to upgrade your design later with any of the listed conditions.
