Since I want to swwep a sensor clock, from 1990MHz to 2010Mhz and the step is 100Khz.
First I though that use a Fractional- N PLL but clock set time is longer than I hope. I hope every switching time is under 1ms.
However, normally it's 3ms.
Second I also think DDS product. It seems to be exactly I want to but I'm not sure.
If then, do you guys have any ideas?
