What are the connection guidelines for the REFCLK pin (GXBR4F) in the Arria 10 10AX115NF40 package?

Description

The Arria® 10 10AX115NF40 device includes a REFCLK GXBR4F pin pair on the right hand side of the device.

The pin can clock an fPLL on the right hand side of the device but cannot clock transceivers on the left hand side of the device.

To use this pin, you must power-up the VCCR_GXB and VCCH_GXB supplies on the right hand side.
