PRODUCTION DATA.
The JESD transmitter uses a PLL that runs off an internal low-dropout (LDO) regulator that provides noise rejection on the external 1.2-V supply. At higher speeds (beyond 4 Gbps), the LDO voltage drops because of increased switching currents. To improve the jitter at higher speeds, restore the LDO voltage with the INC_JESD_VDD register control.
