ADVANCE INFORMATION  
MK2042-01  
Communications Clock Monitor  
ICR O CLOC K  
Description  
Features  
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.  
• Packaged in 16 pin SOIC  
• 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  
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.  
• 3.3 V or 5 V operation  
For switching between clock sources with no  
output glitches or short pulses, use the ICS580 or  
ICS581 multiplexers.
