Bounded uncorrelated jitter (Option J10)

This injects a high probability jitter using a

PRBS generator and low-pass filters.

Table 14. Speciﬁ cations for bounded uncorrelated jitter (BUJ)

Range 0 to 1.1 UI (not to exceed capabilitiy of

delay line used)

PRBS polynomials 2

-1; n = 7, 8, 9, 10, 11, 15, 23, 31

Data rate of PRBS generator 200 Mb/s to 3.2 Gb/s

Filters 50/100/200 MHz lowpass 3rd order

Jitter amplitude accuracy 10% ± 1 ps typical for settings shown

in Table 15.

1. Other settings are not calibrated and do not necessarily generate the desired

jitter histograms for all datarates of the PRBS generator.

2. When using the clock modulator in external clock mode, the external clock

must be > 6.75 GHz. When using the 610 ps delay line in external clock mode,

the external clock must be > 6.75 GHz and z = 4.

Total jitter

A combination of internally generated SJ/SSC/rSSC, PJ, RJ, BUJ

and external jitter (injected using external delay control input) is

possible.

The overall jitter composition does reduce the available jitter

budget of the respective jitter sources.
