I'm testing AD9789-EBZ (REV A) eval board, following the quick start guide many times, but can't get AD9516-1 chip to work.
First time, i connect 2Ghz clock from function generator directly to AD9789 via S1 (HF_DACCLK). Load AD9789_SPIsettings_Int_Sine_Wave.txt" file to eval board via usb cable using "AD9789 SPI" program, and there is a 120Mhz Sine wave in oscilloscope. So AD9789 is running.
Second, i want to generate 2.3Ghz clock using onboard AD9516. I connect 95.573Mhz / 0dBm ref clock to S6 (REF_CLK_IN of AD9516), move JP11 to position 2-3 to turn on AD9516 chip. After that, load "AD9516_SPI_settings_out0_out2_ref_95MHz.txt" file using "AD9516_Load" program , but nothing happen at output of AD9516.
LD test point of AD9516 alway at low level.
Please tell me if i setup hardware or software wrong.
I'm using win7 32 bit.
This is a good question. The AD9516 is indeed our part, but the AD9789 team did the implementation.
Here's the AD9516 user's guide, which may be helpful.
I'm happy to assist you, but if you ask the AD9789 team first, they may be able to nail the issue right away. If not, let me know and I'll help troubleshoot it.
