Part Number: ADC34J43EVM
Other Parts Discussed in Thread: LMK04828,

In ADC34J43EVM, it seems some power pins for LMK04828 are designed to share same power rails.  What's the reason to do like this?

    Diverger,

    Some supplies are more sensitive than others. This is why some are separated from others. The high speed clocking forum can provide more insight about this device if necessary.

    Regards,
