Abstract
The present invention switches between a first clock signal (CLK) and a second clock signal (CLK). Each input signal is buffered by a corresponding tristate buffer (TBUF, TBUF). A multiplexer (MUX) receives the tristate buffer outputs and selects one clock signal in response to a multiplexer control signal (MUX_SEL). A control stage (CONTROL) received a clock selection signal (SEL) and provides multiplexer control signal (MUX_SEL). A change in multiplexer control signal (MUX_SEL) is triggered by a next edge of target clock (CLK) following a delay. This prevents glitches in the output signal.
