In zero delay mode the REF input clock is used as reference clock at the PFD. The FB_P clock (LVCMOS) or FB_P/N clock (differential) can be used to feed an external source as feedback clock to the PFD. The external feedback path is recommended for zero delay operation. Moreover there is an additional internal feedback path which is sourced by output channel 2.
