8. Connectors
There are four connectors on the FMC. One HPC FMC connector provides connectivity to the Main
Board (J3) and another HPC FMC connector (J8) is for a second (stacked) TB-FMCH-HDMI4K, enabling
additional HDMI source and sink ports. The other two connectors are the HDMI source and sink
connectors, located on the front edge of the card.
Note:
Only stack FMCs that are identical (i.e. same part number and same revision). Do not attempt to
stack different FMCs. Stacking FMCs of different types or revisions could cause damage.
8.1. HPC FMC Connector to Main Board
The HPC FMC connector used to mate to the Main Board (carrier) is Samtec ASP-134488-01.
Table 8-1 shows the FMC connector pin assignment. In this table the C2M direction means
carrier-to-mezzanine, which is thus, an input to the FMC. The M2C direction means mezzanine-to-carrier,
which is thus, an output from the FMC. ‘BI-DIR’ means bi-directional, so the signal direction could be
either an input or an output. Pins not included in the table are unconnected, including all HA[0:23] and
HB[0:21] signals.
