To realize a system in which a timing constraint associated with performing inter-symbol interference reduction is relaxed.
A system for relaxing a timing constraint associated with reducing inter-symbol interference (ISI) of input data comprises: a speculative analog circuit configured to receive input data at a first clock rate, add an inter-symbol interference (ISI) cancellation value to the input data to generate first speculative data, and subtract the inter-symbol interference cancellation value from the input data to generate second speculative data; and a sampling circuit communicatively coupled to the speculative analog circuit and configured to sample the first speculative data and the second speculative data at a second clock rate that is one-fourth of the first clock rate such that a timing constraint associated with performing the inter-symbol interference reduction is relaxed.
