Filed: 1988-06-13
Abstract: PURPOSE:To attain accurate duty correction by detecting the duty of a recovered clock and controlling the delay of a variable delay circuit so that the duty is nearly 50%. CONSTITUTION:A reception clock (a) whose duty is not 50% and incoming to a clock terminal 15 is subject to 1/2 frequency division and extracted as a 1/2 frequency division clock (b).
