This paper presents an approach to analyzing Edge Dummy and modeling of gated-oscillator (GO) -based CDRs and D.e.te...r G.t.. predicting their performance aspects such as jitter tolerance (JTOL) and frequency tolerance (FTOL). It is shown that high JTOL of this topology in addition to DD their acceptable FTOL and flexible topology, have made them very suitable for short-haul multi-rate EDET i_i-EDET L1 1 L. applications.
