Technical Description
4.1
Pinouts
The signal direction is from the module’s view. For example,
PCIE0_TX0_N, pin T90, is
an output from the module and an input to peripheral devices on the carrier.
The f ollowing table gives an overview of the 314
pins of the module’s edge finger.
For a detailed connector description see chapter 5.1. The pins will be described in
chapter 4.10 and the f ollowing sections.
The signal names in the f ollowing two tables do not show all available options f or
each pin. Pin multiplexing can only be implemented in combination with the
vendor’s datasheet.
