10 Conclusion

The LMK5C33216 Network Synchronizer device, along with a compliant TCXO or OCXO, meets or exceeds the requirement set in ITU-T G.8262/Y.1362 (07/2010) and Amendment 2 (10/2012).

Notable features of this high performance device includes:

  • Hitless Switching with minimal phase transients (< 100 ps)
  • Ultra High-Performance VCO allows use of a low-cost holdover reference without sacrificing performance
  • High-Performance DPLL Channel with Programmable loop bandwidth for jitter and wander filtering suitable for EEC Option 1 and EEC Option 2
  • Reference Priority Selection, Gapped Clock and Runt Pulse Detectors, Automatic/Manual Switchover, Holdover, and Tuning Word History
