Not Subject to NDA
HSIC Interface (Optional)
The application processor exposes a High-Speed Inter-Chip (HSIC). HSIC eliminates the
analog transceiver from a USB interface for lower voltage operation and reduced power
dissipation.
Further details will be provided in a future release of this document.
SGMII Interface
The SOC includes an integrated Ethernet MAC with an SGMII interface, with the following
key features:
This interface can be directly connected to external Ethernet devices which use
SGMII interface.
When enabled, an additional network interface will be available to the Linux
kernel.
Further details can be found at Ref 8: ETH_Expansion_board_Application Note
8.3.1. Ethernet Control interface
When using an external PHY for Ethernet connectivity, the LE910Cx also includes the
control interface for managing the external PHY
Table 27 lists the signals for controlling the external PHY
