I'm working with EVAL-AD9643 Evaluation Board (http://www.analog.com/en/design-center/evaluation-hardware-and-software/evaluation-boards-kits/EVAL-AD9643.html#eb-overview).
I want to communicate with AD9643 chip via SPI, so I have just connected some "Test point" in Development kit with SPI pin in my Microchip for test:
+TP609 CYP_SCLK ---- SCLK
+TP605 CYP_CS ---- CS
+TP608 CPY_SDI ---- MOSI
+TP607 CPY_SDO ---- MISO
Power supply: Adapter 6V -2A
Don't have any configure AD9523 to suppy clock to AD9643.
Mutual GND between EVAL-AD9643 and my Microchip.
Firstly, I just want to read ID of AD9643, I sent a command following guideline document to read register 0x01. You can see the timing figure I attached in mail with name: timing.png
In Timing figure:
+ Yellow line ---- SCLK
+ Pink line ----- MOSI
+ Blue line ----- MISO
You see I had sent command with read request bit, but I get nothing in MISO line. I don't know the problem, I had checked the power supply is ok, all test point are connected right.
I don't know why I can't get respond from AD9643. Can you help me how I can solve this problem? Should I do another config before read ID from AD9643? Input Clock is request to make AD9643 work?
Thank you for your attention.
