USB Port #3, coming out from SMARC

®

 module, could support OTG functionalities (it depends 

on the functionalities offered by the SMARC

®

 module used, however). 

For this reason, this port is carried out through a standard type-C Socket, type Amphenol p/n 
12401610E4#2A, described in the table on the left. 
This  USB  Type-C  port  CN9  has  Power  Delivery  functionality,  made  possible  by  the  source 
controller  on  SM-B79  carrier  board  with  integrated  1.5A  @5V  USB  power  switch.  This  IC 
controller does monitor USBC_CC1 / USBC_CC2 to detect when a USB sink is attached and 
applies  power  to  VBUS_C  with  the  defined  current  sourcing 
capability (1.5A @5V). 

USB  Type-C  supports  USB  2.0,  USB  3.0  and  USB  3.1  Gen  2 
standards. This support, however, is strictly related to SMARC

®

 module features on USB Port 

ed to refer to SMARC

®

 module user manual intended to be used. 

In addition, USB Type-C is a flippable connector, meaning that this interface is designed in a 
way that the plug can be flipped relative to the receptacle.  The redundancy for the signal on 
Row A and B is included only to provide a flippable connector. 

The Power Delivery controller on SM-B79 carrier board by reading channel configurations pins 
USBC_CC1 and USBC_CC2 will drive the multiplexer on board to correctly re-route the data 
on the employed differential pairs through the connector.
