WebApr 14, 2015 · This brief presents an adaptive continuous-time linear equalizer (CTLE) and one-tap decision feedback equalizer (DFE) using the spectrum balancing (SB) method. The SB method is extended for not only CTLE but also DFE with the aid of gain characteristics of one-tap DFE. Thus, adaptation loops for each equalizer type are merged to a single … WebOct 21, 2015 · DFE (decision feedback equalization) uses a decision circuit as part of its feedback loop. CTLE technology doesn't change for PAM4 signaling. Tx FFE doesn't change in principle, though with four different symbol levels, it changes in practice. But …

WebMar 22, 2012 · If the DLE CTLE is designed to equalize for 3 pre-cursor pulses and 5 post-cursor pulses about the main pulse, then the CLE CTLE will have N*9 taps. The output of the DLE CTLE will further be sampled at one point per data time interval for data detection. The DLE CTLE will only cancel ISI at the data detection sample points. WebOct 1, 2015 · A termination resistor calibration module is used at the receiver's input to reduce the return loss. The CTLE equalises the received data. Then the data pre-amplified by the CTLE is transmitted to the DFE block, which consists of three sampling paths. The boundary path and the data path are responsible for the edge and data sampling.
