I am trying to interface eval board ad9910 with external microcontroller.
I was trying with following specs
Ref clock 1GHz (without using any internal dividers)
This setting worked properly with evaluation board GUI.
With same register values I am trying to write through SPI.
Register 0x00 - 0x00000002
Register 0x01 - 0x00400820;
Register 0x02 - 0x1D3F4150
Register 0x03 - 0x00007F7F
Register 0x0E -0x08b50000, 0x00418937
But its not giving any output.
All jumpers i have enabled and disabled as written in external control jumper settings.
Profile 0, 1, 2 are grounded as I am using profile 0 for writing tuning word.
I am using 6 wires to interface with microcontroller
MASTER_RESET, IO_RESET, CSB, SCLK, SDIO, IO_UPDATE.
I am attaching keil logic analyser output also.
Sorry its an merged image.
Please can anyone advice me whats going on wrong or did i miss anything??
