MX8 SOM External Interfaces
General
The SOM incorporates three Hirose DF40 board-to-board headers. The
selection of the Hirose DF40 is due to the following criteria:
•
Miniature (0.4m pitch)
•
Highly reliable manufacturer
•
Availability (worldwide distribution channels)
•
Excellent signal integrity (supports 6Gbps)
o
Please contact Hirose or SolidRun for reliability and test result data.
•
Mating height of between 1.5mm to 4.0mm (1.5mm to 3.0mm if using 70-pin Board- to-
Board header). SR-SOM-MX6 headers are fixed, the final mating height is determined by
carrier implementation.
Supported Interfaces
