ABSTRACT:
A delay circuit externally adjustable for the delay time "n" as desired, which comprises a FIFO (FIRST-IN, FIRST-OUT) type memory, a self-load counter, and a decoder circuit. In addition to a data signal, an input clock is inputted to the memory as the write clock and the read clock. The self-load counter operates in synchronization with the input clock, and loads a setting of a load value-designating signal at a prescribed number of counts. The decoder circuit receives the output of the self-load counter which has a prescribed cycle, and outputs a reset signal with the same cycle to the memory. This cycle determines the delay time. The delay circuit allows a greatly reduced number of ICs used as compared with the prior art, even for increased delay times.
