Abstract
A timing based adaptive equalization circuit ( ) dynamically monitors a signal received at an input terminal ( ) and compensates for attenuation losses in the transmission of the signal by adjusting an equalization value that increases or decreases the equalization of the signal. A digital phase locked loop control circuit ( ) centers the transition of the equalized signal in a delay line circuit ( ). An analog delay locked loop circuit ( ) provides a fixed throughput time for matching delay elements of delay line circuits ( and ) in the adaptive equalization circuit ( ). Timing signals propagating in the delay line circuits ( and ) are stored in sampler circuits ( and ). The equalization value for equalizing the input signal is adjusted based on stored logic values of specific storage elements in the sampler circuits ( and ).
