TSER953: TSER953 CLKIN input specifications

Part Number: TSER953

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.
