2.12 USB OTG Interface – J8

A USB Type A connector is routed to the SOM via header JX3 pins 63, 67, 69 and 70. In USB OTG Host
mode (default), this interface sources VIN_HDR (+5.0V) power onto the USB_VBUS rail via power switch
(U10) when an active high control signal is present on USB_OTG_CPEN (JX3.70).

This signal is level translated from SOM 3.3V to VIN_HDR via Q14 as shown below. The USB_OTG_ID
signal is brought out to JX3.63 via R23 to allow Host or Device selection.  When grounded the interface is
initially set to host mode, when floating the interface is in device mode. Once connected, the roles can
change via the Host Negotiation Protocol (HNP).

•

By default, the PZCC-FMC-V2 ships i

n USB Host Mode, with capacitors C76/C79 placed and R87

set to 10K

Ω

.

•

To change the mode from Host to OTG, change R87 from 10K

Ω

to 1K

Ω

, and remove capacitors

C76/C79.

•

To change the mode from Host to Device, leave R87 at 10K

Ω

, and remove capacitors C76/C79.

USB Interface protection

The 2.0 OTG data lines (D+/-) are ESD protected using a Bourns diode array (D12), PN:
CDSOT23-SR208 as shown below.
