NOTES:

1. Determined with 2x (G)MCH DDR/DDR2 Buffer Strength Settings into a 50

Ω to 0.5xVCCSM

(DDR/DDR2) test load.

2. Specified at the measurement point into a timing and voltage compliance test load as shown in

Transmitter compliance eye diagram of PCI-E specification and measured over any 250 consecutive TX

Uls.

3. Specified at the measurement point and measured over any 250 consecutive Uls. The test load shown

in Receiver compliance eye diagram of PCI-E specification should be used as the RX device when

taking measurements.
