Abstract
A multiphase clock generating circuit includes a multiphase clock generator that produces a plurality of multiphase output signals at a first frequency and a multiphase divider with delayed reset control. The multiphase divider with delayed reset control is operatively coupled to receive the plurality of multiphase output signals at the first frequency and further operative to produce a plurality of multiphase output signals at a second frequency based on reset control information. As a result, an interface can be supplied with and switch between multiphase clock at different frequencies within a short amount of time with reduced power consumption and circuit area.
