ICS580-01
Glitch-Free Clock Multiplexer
Description
The ICS580-01 is a clock multiplexer (mux)
designed to switch between 2 clock sources with no
glitches or short pulses. The operation of the mux is
controlled by an input pin but the part can also be
configured to switch automatically if one of the
input clocks stops. The part also provides clock
detection by reporting when an input clock has
stopped.
For a clock mux with zero delay and smooth
switching, see either the ICS581-01 or ICS581-02.
