AD9082 TMU_REFP connected to AVDD2 instead of DVDD1P8 on the EVM


The AD9082-FMCA-EBZ evaluation board connects TMU_REFP to AVDD2 even though the AD9082 datasheet states that this pin should be connected to DVDD1P8:

From the AD9082 datasheet:

Some questions:

  • Should TMU_REFP be connected to DVDD1P8 or AVDD2?
  • What is the current requirement for TMU_REFP?
  • Also, why does the AD9082-FMCA-EBZ evaluation board run DVDD1P8 at 2V instead of 1.8V?

Thanks for the help.

Changed title for accuracy.
