I am trying to find appropriate handling guide for unused output channels of ADCLK846 especially in CMOS channel as attached schematics.. do we have guideline or don't care?
Unused outputs (of either type) can be left floating. However, it's critical to terminate the LVDS outputs that you're using with 100 ohms across the differential pair before any decoupling caps.
Appreciate on your confirmation. Yes, of course they should put 100ohm Term R before AC coupling cap or the receiver stage.
