For data rate ≤3.2 Gbps, connect VCCR_GXBL/R to either 1.1-V or 1.15-V power supply. For data rate >3.2 Gbps, connect VCCR_GXBL/R to a 1.15-V
power supply. For details, refer to the Arria V GT, GX, ST, and SX Device Family Pin Connection Guidelines.
The transmitter REFCLKphase jitter is 30 ps p-p at bit error rate (BER) 10-12.
