MEASURING JITTER
The test method used to obtain the timing jitter value given in
the AC Electrical Specification table is based on procedures
and equipment described in SMPTE RP 192-1996. The rec-
ommended practice discusses several methods and indica-
tor devices. An FFT method performed by standard video
test equipment was used to obtain the data given in this data
sheet. As such, the jitter characteristics (or jitter floor) of the
measurement equipment, particularly the measurement ana-
lyzer, become integral to the resulting jitter value. The
method and equipment were chosen so that the test can be
easily duplicated by the design engineer using most stan-
dard digital video test equipment. In so doing, similar results
should be achieved. The intrinsic jitter floor of the CLC021’s
PLL is approximately 25% of the typical jitter given in the
electrical specifications. In production, device jitter is mea-
sured on automatic IC test equipment (ATE) using a different
method compatible with that equipment. Jitter measured us-
ing this ATE yields values approximately 50% of those ob-
tained using the video test equipment.
DS101368-9
Connect LOCK DETECT to TPG ENABLE for test pattern generator function.
Remove RP1 & RP3 and replace RP2 & RP4 with 50
resistor packs for coax interfacing.
Install RP1-4 when using ribbon cable for input interfacing.
This board is designed for use with TTL power supplies only.
