Dear sir /madam,
I have a problem when I use TI DAC5689: my system clock is 100MHZ, (the frequency of the signal which I sent to DAC5689 is 1MHZ) ,how I set the CLK1 and CLK2 of DAC5689 ? I use differential clock for all the clocks and configure the DAC5689 at dual clock mode.
Now I set the CLK1 at 100MHZ and CLK2 at 200MHZ, but the analog output wave is distortion.
Can you give me a reference value of the CLK1 and CLK2?
At the same time, I also have a question about the input signal SYNC. How does it works ? I set TXENABLE 1.8V and don’t use SYNC. Is that ok?
Thank you very much.
