AD9864
Production
The AD9864 is a general-purpose IF subsystem that digitizes a
low level, 10 MHz to 300 MHz IF input with a signal bandwidth
ranging from 6.8 kHz to 270...

Our product is using AD9864, by out test, when the input IF signal with level of -90dBm directly into AD9864, and the DSP capture AD9864 SSI output IQ data then draw it with Matlab, the data is almost noise, we can't see valid signal. For -70dBm input or -30dBm input, the IQ data looks ok.
So, what's the possible reason for my problem, hardware or AD9864 configuration issue? Could anyone help me? Also I want to know what's the smallest input level that AD9864 can accept.
Here is my AD9864 register setting. And my IF input freq is 73.35MHz, LO freq is 71.1MHz.
Hi PMH,
I don't have any other questions now. I am going to buy one EVB board to do test.
You did great help to me, how should I thank you for this? I there any feedback system of your company that I want to thumb up for you.
