A clock signal supply system.

摘要

A clock supply system is disclosed for automating accurate phase adjustment of a plurality of clock signals (125 a - d), each of which having a different phase from each other. The system compring means (115) for generating a reference signal, said reference signal being a phase reference of the clock signal designated by a select signal, and a plurality of pairs of variable delay circuits (120 a - d) and comparator circuits (121 a - d) for outputting said plurality of clock signals (125 a - d), each of which being phase-controlled by said reference signal. <IMAGE>
