The first release under github.com/version2beta/pll. Version numbers below v0.3.0 belong to an earlier, withdrawn API and do not build under this module path.

  • Rate: an exact number of units per second, from UnitsPerSecond or BitsPerSecond.
  • Pacer: evenly spaced, numbered slots at an exact rate, with Due, Claim, Skip, NextDue and a trim in parts per trillion. Times never drift and the hot paths do not allocate.
  • Span: a run of handed-out slots with their exact times, and an iterator over them.
  • Follower: a type-II phase-locked loop configured by bandwidth and damping, with a lower-envelope window for jittery delivery, outlier rejection, steps when the other clock jumps, lock and holdover states, and a running jitter estimate. Its Trim drives a Pacer.
  • cmd/pllsim: a deterministic simulator that runs the follower against realistic clocks and prints what it measured.
