Description. The serdes.DFECDR System object™ adaptively processes a sample-by-sample input signal or analytically processes an impulse response vector input signal to remove distortions at post-cursor taps.. The DFE modifies baseband. SerDes design, and integration of the constantly advancing optimization techniques available in the scientiﬁc community. 1.1. System Background A typical single lane SerDes top level model is shown in Figure2, that consists of a transmitter (TX) that modulates a signal with incoming bits, a channel representing the transmission media, such as a. In summary, the SerDes receiver architecture 200 may optimize pulse shaping for MM-CDR; reduce latency and improve jitter tracking as a result due to CDR tapping from an intermediate node in the equalization data path; reduce and/or eliminate coupling issues between CDR adaptation and equalization adaptation; provide a wider operating range of.
