Can I supply VCCA_GXB[L,R] with 2.5V if I intend to use ATX PLLs on Stratix V GX, GS, and GT devices?

Description

No, when using ATX PLLs to clock your transceiver channels, you must supply VCCA_GXB[L,R] with 3.0V for production Stratix® V GX, GS, and GT devices.

For details of VCCA_GXB voltage requirements for Stratix V GX engineering silicon devices, please refer to the device errata sheet.
