I was looking into MC34VR500V3ES PMIC for powering LS1021A.
This chip has a hardcoded configuration for DDR 4 VTT termination of 0.6V which can eliminate my I2C requirement.
But this does not provide the 1.35V (X1VDD, required for Serdes) on any outputs.
I assume i need to use an external LDO for 1.35V if i do not use I2C. Is it correct?
