NOTES on DIF Output AC Specs: (unless otherwise noted, guaranteed by design and characterization, not 100% tested in production).
1Measurement taken for single ended waveform on a component test board (not in system)
2 Measurement taken from differential waveform on a component test board. (not in system)
3 Slew rate emastured through V_swing voltage range centered about differential zero
4 Vcross is defined at the voltage where Clock = Clock#, measured on a component test board (not in system)
5 Only applies to the differential rising edge (Clock rising, Clock# falling)
6 Total distributed intentional SRC to SRC skew. PCIE Gen2 outputs (SRC3, 4, 6 and 7) will have 0 nominal skew. Maximum allowable interpair skew is 150 ps.
7 The max voltage including overshoot.
8 The min voltage including undershoot.
9 The total variation of all Vcross measurements in any particular system. Note this is a subset of V_cross min/mas (V_Cross absolute) allowed. The intent is to limit Vcross
10 Matching applies to rising edge rate for Clock and falling edge rate for Clock#. It is measured using a +/-75mV window centered on the average cross point where Clock rising
11 For PCIe Gen2 compliant devices, SRC 3, 4, 6, and 7 will have 0 ps nominal skew.
