Configuration and Operation
Note that another USB OTG transceiver is reserved in the ADS which provides by MC13783 (U86). In
the default factory setting, it disconnects from CPU by zero ohm resistor packs (RP24 and RP25). This
transceiver is reserved for some users to evaluate the MC13783 (U86).
2.3.6
The ADS provides a USB On-The-Go (OTG) High Speed (480M bps) interface that uses a Phillips
ISP1504 USB ULPI transceiver connected to J9, a mini AB USB connector. It can also operate at Full
Speed (12M bps). The interface can function as either a USB host or USB device. The interface provides
power on the USB bus in host mode. This power may be supplied by the Phillips part or from the external
5 volt power source through a MIC2536 power switch. For details on the operation of this USB interface,
refer to the i.MX27 data sheet. Figure 2-5 shows this USB interface connection.
2.3.7
The ADS provides a USB High Speed (480M bps) interface that uses a Phillips ISP1504 USB ULPI
transceiver connected to a type A USB connector, J7. It can also operate at Full Speed (12M bps). The
interface can function only as a USB host. The interface provides power on the USB bus. This power may
