AM5749: SATA signals dynamic

Hello,

The VDDA_SATA power pins of the AM5749 must be connected to the 1V8. Do we need a buffer between the SN75LVCP412A redriver and the CPU to leveling the voltage?

On the schematic of the EVM board TI_AM57CXEVM_REV_A3a, the PCIe power pins of the CPU are supplied with 1V8 as well but there is no buffer between the mPCIe connector and the CPU (only AC coupling capacitors). That why I wondering if a buffer is needed for the SATA.

Thanks,

Regards,

Sylvain.
