Hi Santiago,

TICSpro device profile includes a frequency planner and there is also PLL1 & PLL2 loop filter calculator included.

You can also send me your frequency plan and I can generate a configuration for you.

Best regards

Ok, I'm looking for the following frequencies at the outputs: 500kHz, 40MHz, 60MHz, 100MHz and 200MHz.
You can suggest clkin and vcxo.
Best Regards,
Santiago

Hi Santiago,

You can use 100MHz VCXO for this frequency plan. Here is an example configurations:

VCO for PLL2 is running at 6GHhz and Prescaler 5 is used resulting in clock distribution frequency of 1200MHz. Following outout dividers will result in all the frequencies you are mentioned:
