3.7. Transceiver Power-Down

To maximize power savings, enable PMA hard power-down across all channels on a side of the device where you do not use the transceivers.

The hard power-down granularity control of the transceiver PMA is per side (Arria V GX & Arria V GT) or per transceiver bank (Arria V GZ). To enable PMA hard power-down on the left or right side of the device, ground the transceiver power supply of the respective side.

VCCE_GXBL and VCCL_GXBL must be connected either to the required supply or to GND. The VCCH_GXBL pin must always be powered.
