Abstract
A system includes a decision feedback equalizer (DFE). The DFE includes a first summing node, a first synchronization latch, a second synchronization latch, a first feedback latch, and a first feedback shift register. The first summing node is coupled to a data input of the DFE. The first synchronization latch receives data from the first summing node. The second synchronization latch and the first feedback latch receive data from the first synchronization latch. The first feedback shift register is coupled to an output of the second synchronization latch or the first feedback latch. The first feedback shift register includes sequentially coupled shift latches. A first of the shift latches data received from the second synchronization latch or the first feedback latch and provides data to the first summing node. First alternate ones of the shift latches are configured to provide feedback data to the first summing node.
