DC specs are not applicable due
to the pull-up/pull-down resister that is required on the board.
3. BSEL2, CFG[1:0] and TCK signals reference VCC, not VTT.
4. At VCC180 = 1.7 V.
5. Specified at the measurement point into a timing and voltage compliance test load as shown in
Transmitter compliance eye diagram of PCI Express* specification and measured over any 250
consecutive TX Ul’s. Specified at the measurement point and measured over any 250 consecutive ULS.
The test load shown in receiver compliance eye diagram of PCI Express* specification. Should be used
as the RX device when taking measurements.
6. Applicable to the following signals: PCIE_CLKINN/P
7. Measurement taken from differential waveform.
8. Measurement taken from single ended waveform.
9. V
CROSS
is defined as the voltage where Clock = Clock_B.
10. Only applies to the differential rising edge (i.e., Clock rising and Clock_B falling)
11. The total variation of all V
CROSS
measurements in any particular system. This is a subset of V

12. The max voltage including overshoot.
13. The min voltage including undershoot.
