The power supply value describes the budget for the DC (static) power supply tolerance and does not include the dynamic tolerance requirements.
Refer to the PDN tool for the additional budget for the dynamic tolerance requirements.
This is also applicable to HPS power supply. For HPS power supply, refer to tRAMP specifications for standard POR when HPS_PORSEL = 0 and tRAMP
specifications for fast POR when HPS_PORSEL = 1.
The power supply value describes the budget for the DC (static) power supply tolerance and does not include the dynamic tolerance requirements.
Refer to the PDN tool for the additional budget for the dynamic tolerance requirements.
Altera recommends increasing the VCCE_GXBL and VCCL_GXBL typical value from 1.1 V to 1.2 V for Cyclone V GT and ST FPGA systems which
require full compliance to the PCIe Gen2 transmit jitter specification. For more information about the maximum full duplex channels recommended
in Cyclone V GT and ST devices under this condition, refer to the Transceiver Protocol Configurations in Cyclone V Devices chapter.
Altera recommends increasing the VCCE_GXBL and VCCL_GXBL typical value from 1.1 V to 1.2 V for full compliance to CPRI transmit jitter specifica‐
tion at 4.9152 Gbps ( Cyclone V GT and ST devices) and 6.144Gbps ( Cyclone V GT and ST devices only). For more information about the
maximum full duplex channels recommended in Cyclone V GT and ST devices for CPRI 6.144 Gbps, refer to the Transceiver Protocol Configura‐
tions in Cyclone V Devices chapter.
