Features


PTP timing features

  • PTP Grandmaster selection - automatic or manual PTP master/slave mode selection.
  • Powerful network delay analysis - full time-alignment in the slave over hostile networks (Layer 2 or layer 3 networks).
  • Dynamic adaptation - to network delay variations. Network loading change tolerant (e.g., ramps and steps).
  • Time alignment - better than ±1 μs on a managed 10-switch GbE network under G.826120 test conditions.*
  • Frequency alignment - better than ±10 ppb on a managed 10-switch GbE network under G.826120 test conditions.*

TDM timing features

  • Programmable TDM timing bandwidth - for wander and jitter tracking/attenuation, 0.1 Hz to 70 Hz in 10 steps.
  • Automatic hit-less source switchover - on loss of input.
  • Output clock phase adjustment - in 6 ps steps to ±200 ns.
