HDMI
The Intel
®
BD82QM67 or BD82HM65 (QM67 or HM65) PCH on the conga-BM67/BS67 supports integrated HDMI, which is multiplexed onto the
PCI Express Graphics (PEG) interface of the COM Express connector. The Intel
®
QM67 or HM65 provides three ports capable of supporting
HDMI. See section 7.5 of this document for more information about enabling HDMI peripherals.
Note
For more information about implementing a HDMI interface on COM Express™ carrier boards, refer to application note AN17_HDMI_DP_
Implementation.pdf, which can be found on the congatec website.
4.2.4
DisplayPort (DP)
The conga-BM67/BS67 offers three DP ports, each capable of supporting link-speeds of 1.62 Gbps and 2.7 Gbps on 1, 2 or 4 data lanes.
The DP is multiplexed onto the PCI Express Graphics (PEG) interface of the COM Express connector. The DisplayPort specification is a
VESA standard aimed at consolidating internal and external connection methods to reduce device complexity, supporting key cross industry
applications, and providing performance scalability to enable the next generation of displays. The Intel
®
BD82QM67 or BD82HM65 (QM67
or HM65) PCH can support a maximum of 2 DP ports simultaneously. See section 7.5 of this document for more information about enabling
DisplayPort peripherals.
Note
For more information about implementing a DisplayPort (DP) interface on COM Express™ carrier boards, refer to application note AN17_
HDMI_DP_Implementation.pdf, which can be found on the congatec website.
4.2.5
PCI Bus
The PCI bus is implemented using the Intel
®
certified Pericom PI7C9X113SL PCIe to PCI bridge and is connected via one of the eight PCI
Express lanes offered by the conga-BM67/BS67. The PCI bus complies with PCI specification Rev. 2.3 and provides a 32bit parallel PCI bus
that is capable of operating at 33MHz. The PCI bus provides support for up to 4 bus masters.
Note
The PCI interface is specified to be +5V tolerant, with +3.3V signaling.
