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 CLC020’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.
The jitter test setup used to obtain values quoted in the data
sheet consists of:
National Semiconductor SD020EVK, CLC020 evaluation
kit
Tektronix TG2000 signal generation platform with DVG1
option
Tektronix VM700T Option 1S Video Measurement Set
Tektronix TDS 794D, Option C2 oscilloscope
Tektronix P6339A passive probe
75 Ohm coaxial cable, 3ft., Belden 8281 or RG59 (2 re-
quired)
ECL-to-TTL/CMOS level converter/amplifier, Figure 9
Apply the black-burst reference clock from the TG2000 sig-
nal generator’s BG1 module 27MHz clock output to the level
converter input. The clock amplitude converter schematic is
shown in Figure 9.Adjust the input bias control to give a 50%
duty cycle output as measured on the oscilloscope/probe
system. Connect the level translator to the SD020EVK
board, connector P1, P
pins (the outer-most row of pins
is ground). Configure the SD020EVK to operate in the NTSC
colour bars, BIST mode. Configure the VM700T to make the
jitter measurement in the jitter FFT mode at the frame rate
DS100917-9
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.
For optional ECL compatible load: R1A = R2A = 187; R1B = R2B = 124.
All resistances & impedances in Ohms. Values with 3 significant digits are 1%; with 2 digits 5%.
