When implemented as a chip-to-chip interface, the XGMII uses High Speed
Transceiver Logic (HSTL), specified for a 1.5 volt output buffer supply voltage.
XGMII chip-to-chip signals shall comply with EIA/JEDEC Standard EIA/JESD8-
6 using Class I, output buffers. Output impedance shall be greater than 38Ω to
assure acceptable overshoot and undershoot performance in an un-terminated
interconnection.
