1. The FR4 trace between TTP1 and TTP2 is designed to emulate 1-8” of FR4, AC coupling cap, connector and another 1-2” of FR4. Trace width – 4 mils. 100-Ω differential impedance.
2. All jitter is measured at a BER of 10-9.
3. Residual jitter reflects the total jitter measured at TTP4 minus the jitter measured at TTP1.
4. AVCC = 3.3-V
5. RT = 50-Ω
6. The input signal from parallel bit error rate tester (BERT) does not have any pre-emphasis. Refer to Recommended Operating Conditions.
