ZERO DELAY GLITCH-FREE CLOCK MULTIPLEXER
DATASHEET
ICS581-01/02
Description
Features
The ICS581-01/02 are glitch free, Phase Locked Loop (PLL) based clock multiplexers (mux) with zero delay from input to output. They each have four low skew outputs which can be configured as a single output, three outputs, or four outputs. The ICS581-01 allows user control over the mux switching, while the ICS581-02 has automatic switching between the two clock inputs.
The ICS581-01 and -02 are members of IDT’s ClockBlocksTM family of clock generation, synchronization, and distribution devices. For a non-PLL based clock mux, see the ICS580-01.
