Abstract

A clock buffer circuit that generates a local clock signal in response to a system clock signal. The clock buffer circuit includes a buffer circuit for generating the local clock signal in response to an intermediate clock signal. A buffer control circuit generates the intermediate clock signal in response to the system clock signal and the local clock signal. The buffer control circuit provides a variable delay so that, with an additional delay provided by the buffer circuit, the local clock signal has a selected phase relationship in relation to the system clock signal.
