ZERO DELAY GLITCH-FREE CLOCK MULTIPLEXER
Description
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
ClockBlocks
and distribution devices. For a non-PLL based clock mux,
see the ICS580-01.
