A deeper SSC estimator used as a CDR with a low power mechanism based on third‐order architecture is proposed to suppress the disadvantage of the conventional third‐order CDR happening at the switching points of SSC (spread spectrum clocking). For 10 Gbit/s data speed, the depth of its SSC tracking may be up to 10000ppm at 30 kHz which helps to reduce more EMI.
