The SoM Interface consists of three SAMTEC high speed connectors that provide the DSP peripheral signals for use
with a plug in baseboard. The SoM Connector figure shows the connector locations on the back of the board.
These signals are based upon the peripheral signal needs, which allows multiple DSPs to be used with this connec-
tion. These connectors are self-mating and the pinout here reflects the connectors on the EV-SC594-SOM.
The SoM Interface A Connector (P16), SoM Interface B Connector (P20), and SoM Interface C Connector (P15) tables
show the signal associated with each pin on the connectors.
