Note :
1. Specified at the package pins into a timing and voltage compliant test setup. Note that signal levels at the pad will be lower than at the pin.
2. Single-ended voltages below that value that are simultaneously detected on D+ and D-are interpreted as the Electrical Idle condition. Worst-case mar-
3. Multiple lanes need to detect the El condition before the device can act upon the El detection.
4. Specified at the package pins into a timing and voltage compliance test setup.
5. The single-pulse mask provides suffcient symbol energy for reliable RX reception. Each symbol must comply with both the single-pulse mask and the
6. The relative amplitude ratio limit between adjacent symbols prevents excessive intersymbol interference in the RX. Each symbol must comply with the
7. This number does not include the effects of SSC or reference clock jitter.
8. This number includes setup and hold of the RX sampling flop.
9. Defined as the dual-dirac deterministic timing error.
10. Allows for 15 mV DC offset between transmit and receive devices.
