Attenuator Input Jitter Tolerance
(Before Onset of FIFO Overflow or Underflow Protection)
26. Crystal must meet specifications described in CXT6176/CXT8192 data sheet.
27. Jitter measured at the demodulator output of an HP3785A (or equivalent) using a measurement
28. Jitter below 100 kHz and within the attenuator’s input jitter tolerance is not translated or aliased to
measured jitter tolerance using a measurement bandwidth of 1 Hz (10<f<100Hz), 4Hz (100<f<1000
Hz) and 10 Hz (f> 1kHz) centered around the jitter frequency. With a 2
bandwidth not to exceed 20 Hz centered around the jitter frequency. With a 2
other frequencies. Output jitter increases significantly when attenuator input jitter tolerance is
exceeded.
