MK2042-01 - Communications Clock Monitor

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.

Features

  • 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.
  • 3.3 V or 5 V operation Block Diagram VDD GND SELB OE INB INA Clock Loss Det.

ADVANCE INFORMATION I C R O C LOC K 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.
