Hi

 

Hi

Please tell me the register setting for transmitting the test pattern with the AD9434.

 

Instead of EVB, SPI transfer is performed and the value is written to the internal address.

Looking at the data sheet, TestIO is prepared,
After once flowing the register setting sequence once,
When you want to issue ALL 1,
'①Address: 0x0D
Setting: 0x08
'②Address: 0xFF
Setting: 0x01

If you want to alternate 1/0,
'①Address: 0x0D
Setting: 0x48
'②Address: 0xFF
Setting: 0x01
It is a perception that it should be passed, is it correct?

Even if I set the above, it seems that the test pattern is not output well, so I confirmed it.

 

Best Regards

HOD
