CDCLVC1112: Multiple CDCLVC1112: Cascade or Cascode?

Volkan Dogan

Part Number: CDCLVC1112

Hi, I want to use 3x CDCLVC1112 ,which is 1:12 fanout clock buffer, to fan-out 30x clocks. However I am not sure if I should use them as cascade or cascode. Can I clock input directly to 3 cascode of CDCLVC1112 or shall I use 1 of them to cascade the other 2 parts?

Thanks

Hi,

Each fanout buffer will add some additive jitter to the clock, so for best performance it is best to use 1 to cascade to 2 other parts.
