Question:
I have a question on the SPI read command used with the CDCE62002.
When a read command is sent via SPI the CDCE62002 returns the requested register data. From my reading of the datasheet I am not sure whether 28 bits (data field only) or 32 bits (data field plus address field) are returned. Which is the case?
Answer:
On the CDCE62002 the read command returns the Register contents on the MOSI lines on the SPI interface. When you read from the GUI the GUI reads all the bits and displays them as functional setups. The GUI always reads the device memory and displays it on the screen.

Hi Answer:
In "CDCE62005 and CDCE62002 SPI Interface Guide version3", demo writes ".. Register 6, which is at the time holding the value 01h..", But ReadOut bit result is "0x00000106", which means the left - 0x000001 is what Reg#6 's value, and the right - 06 is Reg# addr . is that the case correct ?? From datsheet, it says "28bit data filed" + "4 bits Addr fileds", which is correct ???
