MK2042-01 Datasheet Communications Clock Monitor

Manufacturer: Integrated Circuit Systems

Overview: ADVANCE INFORMATION I C R O C LOC K.

General 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.

Key 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.
