Applications
  • Fibre Channel
  • Gigabit Ethernet
  • Optical Networking
  • PCI Express
  • Router
  • RAID Controller Server
  • System Clocking
  • Any combination of the previous applications

Features Benefits
  • Integration of up to three oscillators, 1 differential and two single-ended
  • More reliable designs and board space saving
  • Frequency range of 1 to 220 MHz with 5 decimal places of accuracy
  • Allows designers to customize the product to their applications
  • Use the same base product in a variety of different applications
  • Ultra low jitter
    • < 1 ps RMS phase jitter (random) or 5.0 ps RMS period jitter
  • Improves total timing margin in high performance designs
  • Tight frequency tolerances of ±25PPM and ±50PPM
  • Provides high stability clock to increase the robustness of their designs
  • Ultra fast lead time (3-5 weeks)
  • Reduce inventory overhead
  • Mitigate shortage risks
