Determined with 2x (G)MCH DDR/DDR2 buffer strength settings into a 50 to 0.5xVCCSM (DDR/DDR2) test
load.
Specified at the measurement point into a timing and voltage compliance test load as shown in Transmitter
compliance eye diagram of the PCI Express* Base 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 the PCI Express* Base Specification. Should be used as the
RX device when taking measurements.
Low voltage PCI Express (PCI Express Graphics/SDVO) interface.
