actually i am using one like i explained above...maybe there is a PLL involved?
That's regular waveform from DDS kind of NCO.Hi,
I´m surprised. The scope picture shows a sinewave, but I expected a square wave as NCO output.
"I think" ... why don´t you verify it by simply connectig the cope to the PLL output?i think pll is the problem. anybody had any idea how to fix it
Expectable if the acquisition clock isn't an even multiply of the output frequency.strange signals which duty cycle is varying
are the system clocks.input OSC_50_B3B;
input OSC_50_B4A;
input OSC_50_B5B;
input OSC_50_B8A;
??? What is the acquisition frequency, actually?i was using acquisition clock as 50 mhz and all those clock to pll are also 50 MHz. but now i changed to MHz which is the output of pll.
I don´t know.but why system clock dont have 50 % duty cycle
hi
really sorry fvm. now its 65 mhz.
but why system clock dont have 50 % duty cycle
thanks
