Abstract
A decision feedback equalizer includes a lookup table device. The lookup table device may include a shift register and memory, or may include multiple shift registers and memories. Near-end crosstalk may be reduced using a lookup table device. Echo in a bi-directional port circuit may also be reduced using a lookup table device.
