PCI Express Graphics (PEG)
The Express-HRR supports the implementation of a x16 link for an external high-performance PCI Express
Graphics card. It supports a theoretical bandwidth of up to 5GT/s. Each lane of the PEG Port consists of a
receive and transmit differential signal pair designated from PEG_RX8 (+ and -) to PEG_RX15 (+ and -)
and correspondingly from PEG_TX8 (+ and -) to PEG_TX15 (+ and -).
SDVO
The PCH provides Serial Digital Video Output (SDVO) functionality and may be alternatively used for one
third party SDVO compliant device connected to Digital Port B.
Table 3-6 provides the pin signals for the COM Express C-D connector.
