I wish to comfirm the following two things: Do REFCLK± pins conform to HCSL electrical standards ? (i can’t see any useful info regarding this, neither DS nor OEM Design Guide). Otherwise please point out to what electrical standard shall REFCLK± conform? Please show how REFCLK± pins are termi…

Our engineering team says that irrespective of the source (i.e. LVPECL, LVDS, CML,HCSL) REFCLK should always conform to AC and DC specifications as mentioned by the spec. FWIW, TX2 does conform to the spec and the source in case of TX2 is CML. [image]
