[introduction] the market grows day and day to the demand of expensive processing capability and low power comsumption, driving processor and MCU to develop to the advanced technology node that uses technology of 5 accept rice. Move to using 1.2V power source and apply to shift and computational application and traditional market (like medical treatment, industry and telecommunication) processor, USB2 interface is a challenge. Because the working voltage of USB2 interface is inferior, need converter ability undertakes notting have seaming communication.

In the choice USB turns the 3 considerations matter that the attention wants when receiving driver includes:

Signal quality or integrality

If the PCB of USB2 interface of the client takes a line longer, if be not used,turn receive driver to be able to encounter signal quality / integrality problem. Use longer PCB to walk along line or cable normally to USB2, need to turn next receive driver to ensure the integrality of USB2 signal.

Size limitation

Great majority application has size restriction, those who support more cabinet solution is small-sized the good choice that enclosing is these application. The IC that favour wisdom riverside offers is smaller than the dimension of congener product 30% , can save PCB space, apply to the application that needs small size.

Flexibility

Offer a variety of configuration, apply to EUSB2 and USB2 application. The Tx of EUSB2 and USB2 signal and Rx have a variety of settings, offer a variety of option, can optimize function.

Item of these 3 considerations conduces to rise to use a sex easily. For example, the USB of any traditional types receives this parts of an apparatus repeatedly, all can work normally, rate is rapidder, can effect is taller. Favour wisdom riverside provides an acquiescent setting, before delivering goods already process designing arrives in every parts of an apparatus. Accordingly, it applies to wide market application, but also can use register watch to undertake optimizing for EUSB2 and USB2.

It still applies to USB2 interface to have the other market that challenges a gender, include medical treatment, industry and telegraphic industry

PTN3222 of favour wisdom riverside supports USB2.0 and EUSB2 V1.1, its one large dominant position is to be able to join low-pressure microprocessor and USB2 peripheral.

PTN3222 turns the portable application that receives driver to be aimed at need small size. It is the most cabinet EUSB2 on the market turns to USB2 receive one of solutions. Turn receive driver measure smaller, end item measure is relevant also decrescent, provide more spaces for batteries and other component.

Following plan institute are shown, PTN3222 is an independent parts of an apparatus.

Revealed in the graph how to join PTN3222 of favour wisdom riverside

The article introduced USB to turn the dominant position that accepts driver reachs his to basically consider matter in 3 when type selecting, PTN3222 of hope favour Zhi Pu can produce an advantage in your product.
