1. The FR4 trace between TTP1 and TTP2 is designed to emulate 1-8” of FR4, connector and another 1-8” 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 Bert does not have any pre-emphasis. Refer to Recommended Operating Conditions.
