CDCE62005: Unused clock output connection

Also, if I Pull up REF_SEL (with 10k Ohm to 3.3v) = use PRI_REF only,

the SEC_REF signals leave them Not connected or connect them to Ground? didn't find also any information about these signals connection when they not in use, in the datasheet

Hi Vicente,

Thank you for your support, please assist regarding my questions below:

1. When I leave outputs float (AUX OUT, U0P, U0N, etc.) will affect the EMI if the board?

2. Is there any difference between the outputs? (U0 - U4) If I need only 3 outputs? core clock 100MHz, sgmii clock 250MHz, and DDR clock 50MHz / 66.6MHz (and connect all to DSP as LVDS)

3. How can I know which filters I need to apply after the 3.3v to VCC_VCO and VCC_PLL? the datasheet mentions these inputs need filters but do not provide the maximum current that they could achieve.

4. What is the difference between PRI_REF to AUX_IN? Do I need to use both of them for my purpose? (connect 3 LVDS clocks mentioned in question 2 to TI GAUSS DSP TMS320C6655)

So as I understood, for my clock usage (to DSP 6655 GAUSS: with core clock 100MHz, sgmii clock 250MHz, and DDR clock 50MHz), I don't need to use AUX_IN only use PRI_REF?
