6.9 Typical Jitter Characteristics

Figure 6-4 , Figure 6-5, and Figure 6-6 show eye diagrams at BERT source output, through calibration traces, and through

810 respectively. Note: 810 adds little to no random jitter. Residual equalization of

≅4 dB at EQ = 0 setting results in slightly

lower deterministic jitter through DUT compared to baseline setup with 7 dB loss.

Figure 6-5. Through Baseline Calibration Trace Setup (7 dB

Loss)

Figure 6-6. Through DS320PR810 (7 dB Loss and DUT EQ = 0)
