ADVANCE INFORMATION

MK2042-01

Communications Clock Monitor

_{ICR O}C_{LOC 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.
