NOTES:
1. Determined with 2x MCH DDR2 Buffer Strength Settings into a 50 Ω to 0.5xV
CCSM
(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 the PCI Express Interface Specification 1.0a 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 the PCI Express Interface Specification 1.0a should be used as
the RX device when taking measurements.
