1Gbps to 12.5Gbps
Passive Equalizer for Backplanes and Cables
Typical Operating Characteristics (continued)
(TA = +25°C, unless otherwise noted. All measurements were done with 1VP-P at the source. Stress pattern: 27 PRBS, 100 zeros, 1, 0, 1,
0, 27 PRBS, 100 ones, 0, 1, 0, 1. Residual deterministic jitter graphs were measured using Tektronix’s FrameScan. Deterministic jitter of
the system was subtracted from the measured value. Eye diagrams acquired by FrameScan include deterministic jitter of the system
(approximately 9ps) but not random jitter. Twin-ax cable: Amphenol Spectra-Strip Skewclear 100Ω 24AWG.)
