WebThe ICS581-01 and ICS581-02 are glitch free, Phase Locked Loop (PLL) based clock multiplexers (mux) with zero delay from input to output. They each have 4 low skew outputs which can be configured as a single output, 3 outputs or 4 outputs. The ICS581-01 allows user control over the mux switching. The ICS581-02 has automatic WebJan 23, 2024 · 1,229. FvM said: The glitch-free feature depends on synchronisation of the mux control signal to the clock input. In a synchronous logic design, other signals than clocks are sampled at clock edges and don't need to be glitch-free outside the setup- and hold window. In other words, it's almost unclear what you want to achieve.
