Abstract
An adjustable logic circuit includes a pulse filter and delay circuit, a state machine and combinational logic circuit, and a data strobe generation circuit. The pulse filter and delay circuit is operative to read an adjustable configuration value and, based thereon, to implement a delay between an internal clock and both a data signal and a data strobe signal, the delay being a fraction of a clock period. The state machine and combinational logic circuit are operative to select a data value from a plurality of data values, and to provide a data signal based upon the data value. The data strobe generation circuit is operative to provide the data strobe signal at a time when both the data signal is valid and the delay is compatible with a predetermined external device.
