How to power up and ADF4350

Category: Hardware

The ADF4350 may become unstable depending on how the power supply rises.

Serial data will be sent several tens of milliseconds after the power supply reaches +3.3V.

There is no problem if +3.3V rises upward.

If there is a dip in the rise of +3.3V, it may unlock on the first data.

Does the ADF4350 initialize the registers or latch the registers and not accept the serial signal depending on how the power is turned on?
