  • Video (54 MHz and 27 MHz)
  • MCU clocking (66 MHz and 33 MHz)

Features Benefits
  • 2-frequency selectable output
  • Enable the reuse of same device in multiple designs or in multiple blocks of the same design
  • 3.5 mA typical power consumption
  • Allow more power budget for system designers
  • Extensive programmability
    • Any frequency (main frequency Fo) up 110 MHz with up to 5 decimal place accuracy
    • Fo/2, Fo/3, Fo/4 and Fo/8 option for the alternative frequency output
    • Voltage options of 1.8V, 2.5V, 2.8V and 3.3V
    • Frequency tolerance from ±25PPM to ±50PPM
  • Allow the designers to use the base product for many designs, minimizing qualification effort
  • Consolidate part numbers and suppliers
  • Re-use of the same base product for many designs
  • Customize specification for optimal system performance
  • Ultra fast lead time (3-5 weeks)
  • Reduce inventory overhead
  • Mitigate shortage risks
