Other Parts Discussed in Thread: TUSB2551A

We are planning to use one of your USB Transceiver(TUSB2551A) for our application.Our application details are attached with this mail.Please escalate me some of the reference schematic using this chip.And also I have attached our chip USB interface signal file ,please check whether the selected USB Transceiver chip will meet the basic requirement for our USB OTG/HOST/DEVICE MCU.

The TUSB2551A predates the USB on-the-go (OTG) specification and therefore does not support OTG applications.

Thanks for the support,Please go through the Schematic example given on the previous mail.Our MCU does act as a Host while we configure the controller to work in host mode.So at that time the pins dedicated for the OTG operation will go to High impedance state(VP,VM& OE signals will be active for the Host operation). Because our application is only intended for USB Host operation not OTG.Please give me a detailed reply for the query.
