I was advised on High-Speed DACs and I will set up a new thread here.
This is a question about the operation of the AD9144(or ADI FMCDAQ2).
My customers are evaluating the AD9144.
My customer is trying to output sawtooth waves from AD9144.
T = 200 nS, + 100 count → -100 count
The customer inputs the code and evaluates the output waveform.
Strangely, the output slope bounces small around 0 count.
Customers suspect this as miscounts.
The FPGA side consists of Xilinx ZC706 and the DAC side is made by ADI FMCDAQ2.
How should I check to isolate it from mistakes in circuit design?
I'd appreciate if you give me expert advice.
