Notes to Table 1–4:
(1) HardCopy IV devices do not require Programmable Power Technology.
(2) In HardCopy IV devices, this power supply is not used.
(3) If the PORSEL pin is connected to VCC, all supplies must ramp up within 4 ms.

Notes to Table 1–5:
(1) If VCCHIP_L/R is connected to the same power supply source as Vcc, the recommended minimum and maximum operating supply levels are
0.87 V and 0.93 V respectively.
(2) The VCCH and VCCL powers are per transceiver block
(3) VCCA_L/R must be connected to a 3.0 V supply if the CMU PLL, receiver CDR, or both are configured at a base data rate > 4.25Gbps. For data
rates up to 4.25 Gbps, you can connect VCCA_L/R to either 3.0 V or 2.5 V.
(4) For data rates up to 6.5 Gbps, you can connect VCCH_GXBL/R to either 1.4 V or 1.5 V.
DC Characteristics
This section lists the supply current, I/O pin leakage current, input pin capacitance,
on-chip termination (OCT) tolerance, and hot socketing specifications.
Supply Current
Standby current is the current the device draws after the device is configured, with no
inputs or outputs toggling and no activity in the device. Because these currents vary
largely with the resources you use, use the Excel-based PowerPlay Early Power
Estimator (EPE) to get supply current estimates for your design.
