Abstract
Accordingly embodiments herein disclose a quarter rate speculative DFE. The quarter rate speculative DFE includes a plurality of sampler circuits connected to an input terminal. The plurality of sampler circuits are configured to sample an input signal into a plurality of data samples in parallel. A plurality of quarter rate look ahead circuit connected to the plurality of sampler circuits. The plurality of quarter rate look ahead circuit is configured to simultaneously perform an align operation and a look ahead operation on the plurality of data samples based on the different clock phases to obtain a plurality of latched outputs. A plurality of multiplexers connected to the plurality of quarter rate look ahead circuit. The plurality of multiplexers is configured to generate two speculative data streams by multiplexing respective correction coefficients of each of the plurality of latched outputs.
