MXH832 PCIe x16 Edge Connector Pin-Out
The MXH832 Edge connector follows PCI Express CEM Specification, Rev. 3.0 section 6 – Card Connector Specification. Signal names
are shown in Table 9. In host mode, the MXH832 is PCIe SIG compliant. The signals in bold are bi-directional, where the direction
depends on if the card is configured for host or target mode. In the case where the MXH832 is configured as a target adapter in an
expansion chassis, it will provide a 100 MHz, non-SSC, reference clock on the /REFCLK- pins. The shaded signals TDI and
TDO are normally tri-stated, but can be configured to provide an alternative 100 MHz, non-SSC, reference clock for PCIe expansion
chassis utilizing these pins instead.
