Claim 15:
16. The circuit of claim 12, the DFE further comprising:
a current input configured to receive a communication symbol from the current clock cycle;
a current adder having a fifth adder input coupled to the current input, a sixth adder input, and a current adder output;
current DFE filter circuitry having current DFE filter inputs and having current DFE filter outputs responsive to the current DFE filter inputs, the current DFE filter outputs correspond to members of a set of possible combinations of the current DFE filter inputs;
a current multiplexer having current multiplexer inputs coupled to the current DFE filter outputs, a current multiplexer output coupled to the sixth adder input, and having control inputs coupled to the first multiplexer output and the second multiplexer output, the current multiplexer configured to connect one of the current multiplexer inputs to the current multiplexer output; and
a current slicer having a current slicer input coupled to the current adder output, and having a current slicer output.
