NOTE 16: PLL characterization:
Short term jitter in open loop or closed loop is defined as the variation within one PLL update period (= within the same video line) of
the clock rising edge. This is measured visually by capturing the clock and displaying it on a digital scope with a persistency of one
video line. Numerically the time instants of the rising edges, at a defined voltage level, of a number of clock cycles (N = 800) are
captured at high sampling rate. From these time instants, the average clock time period is calculated. The deviation between each
actual time instant and the ideal, based on the average clock time period, is defined as a statistically distributed jitter value along
one line. This jitter is measured on both DATACLK1 and DTOCLK3 outputs.
Long term jitter in closed loop is defined as the variation over one video frame of the Nth clock rising edge on each line. This is
measured by capturing the time instant that a defined level on the rising edge of the Nth clock after HS is reached on each line. The
same principle for calculation is used as for short term jitter but now for one sample taken on every line and N = 800 lines.
