User controlled or automatic switching
Clock detect feature
Does not add jitter or phase noise to the clock
Ideal for systems with backup or redundant clocks
Selectable timeouts for clock loss detection
Accepts input frequencies from 0 Hz to 160 MHz
Works with all MK2049-xx to provide enhanced
operation
3.3 V or 5 V operation
Description
The MK2042-01 is designed to switch between
two clock sources. The switching can be externally
controlled by an input pin or configured to switch
automatically if the primary input clock stops.
The part also provides clock detection by reporting
when the primary input clock has stopped.
The MK2042-01 is optimized for use with our
MK2049 family of Communication Clock
Synthesizers. When used together, the
MK2042-01 and MK2049 provide a complete
system for switching to an alternate source when
the primary clock is lost, or for maintaining a
stable frequency on the MK2049 output.
For switching between clock sources with no
output glitches or short pulses, use the ICS580 or
ICS581 multiplexers.
