Why does the Dual Simplex Example Design in GTS JESD204C FPGA IP, with the data path clocking mode set to System PLL and JESD204C DS wrapper set to “Dual Simplex applied on JESD204C PHY,” fail to generate when the data rate exceeds 10,312.5 Mbps?

Description

The Dual Simplex Example Design generation fails when the data rate exceeds 10,312.5 Mbps due to a System PLL clock constraint being violated.
