Hi Support Team
I am planning to use OSC and CLK Generator for CLKIN.
So I was wondering if you could give me the input specifications for CLKIN.
I am wondering how many ppm will be required.
Best regards.
Hello Takahiro-san,
you can use CLKIN with 100ppm. But you need to make sure the Input CLK jitter is below 0.05 UI.
Where the UI is defined as 1/clock_freq for a given clock. For example, when the clock = 50Mhz, the typical UI_CLK_IN is 1/50 MHz = 20 ns.
