Is the explanation of V_REF and V_BIAS on page 7 of the ADF4355 Rev. B datasheet reversed?

The descriptions of V_REF and V_BIAS on page 7 of the ADF4355 datasheet are indeed reversed. However, the pin number and mnemonic assignments are correct. Please follow these assignments for accurate usage.

Fast locking of ADF4356

Question Can you send me a procedure for fast locking of ADF4356? Many thanks Answer I can confirm that it works equally for the ADF4356…you can use the attachedap-note for now ..while I need to update it to reflect the addition of theADF4356/ ADF5356…, the register write/readback description is the same for allparts.

ADF4355, ADF4355-2, ADF4355-3, ADF4356, ADF5355, and ADF5356 evaluation board control software
