Table 85.  Transceiver Power Supply Voltage Requirements for Arria V GZ Devices
Conditions VCCR_GXB and VCCT_GXB 125 VCCA_GXB VCCH_GXB Unit
If BOTH of the following conditions are true:
  • Data rate > 10.3 Gbps.
  • DFE is used.
1.05 3.0 1.5 V
If ANY of the following conditions are true 126 :
  • ATX PLL is used.
  • Data rate > 6.5Gbps.
  • DFE (data rate ≤ 10.3 Gbps), AEQ, or EyeQ feature is used.
1.0
If ALL of the following conditions are true:
  • ATX PLL is not used.
  • Data rate ≤ 6.5Gbps.
  • DFE, AEQ, and EyeQ are not used.
0.85 2.5
125 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.
126 Choose this power supply voltage requirement option if you plan to upgrade your design later with any of the listed conditions.
