  • Non condensing.
  • AC coupled.
  • Into 100 ohm differential termination.
  • 20 – 80 %
  • LOS is LVTTL. Logic 0 indicates normal operation; logic 1 indicates no signal detected.
  • Measured with DJ-free data input signal. In actual application, output DJ will be the sum of input DJ and ΔDJ.
