Abstract
A fast approach to switching between first and second asynchronous clock signals with reduced latency is provided. When the clock select signal indicates a switch from the first clock signal to the second clock signal, the switch is not made immediately. Instead a blanking signal is generated to suppress the glitch before switching clocks internally. The start of the blanking signal is based on the last falling edge of the internal clock signal before the switch and the end of the blanking signal is based on the first falling edge of the internal clock signal after the switch. The first falling edge is the falling edge of the glitch. The glitchy internal clock is logically combined with the blanking signal to generate an output clock signal that is glitch-free.
