2.10.9 USB

The AM275x EVM features a USB 2.0 Interface through a USB Type-C connector (J25) that supports data rates up to 480Mbps. USB Type-C connector 2 (J25) can be used for data communication and/or a power supply connector to the AM275x EVM. The USB Type-C port is configured as a dual role port (DRP) port using the Dual PD controller (TPS65988DHRSHR), which means it can act either as a Host or a Device. The role of the port depends on the type of device getting connected to the EVM through the connector, and its ability to either sink or source. When the port is acting as a Downstream-Facing Port (DFP), it can source up to 5V at 500mA.

USB 2.0 Type-C connector 2 (J25) data lines, USBC_CONN2_DP and USBC_CONN2_DM are provided with a choke and an ESD protection device. VBUS_TYPEC2 to the Am275x SoC's USB0_VBUS is provided through a resistor divider network to support (5V-30V) VBUS operation.

A Common Mode Choke (DLW21SZ900HQ2B) is provided on USB Data lines for EMI/ EMC reduction. An ESD protection device (ESD122DMXR) is included to dissipate ESD strikes on USB2.0 DP/DM signals. ESD protection devices (TPD1E01B04DPLT) are included on CC signals for both USB-C connectors 1 and 2 (J24 and J25). A surge protection device (TVS2200DRVR) is included on the VBUS rail of Type-C Connector 2 (J25) to dissipate ESD strikes.
