architecture of analog data acquisition

Other Parts Discussed in Thread: TUSB3410

Hi,

I am kind of new to the electronic hardware design. My project is to implement analog data acquisition via USB interface of the PC. The signal I have is a pulse (temporal width varies from us to ms) and the repetition rate is around 6Hz.

I looked around the website and found there are few kinds of USB IC available. 

What I have in mind is: (12 bit) A/D converter + USB transceiver + PC

Is this gonna work? Or could you suggest me a better solution? Thank you very much!

    Joyer,

    Unfortunately your system will not work as proposed.  A USB Transceiver needs to have a USB engine behind it which in your system you do not have.  the transciver is essentially just the analog signalling portion of a USb device.  The core engine is what decodes/encodes USB prototocol for communication to the host PC.

    A couple of ideas would be to use something either like the TUSB3410 (USB-to-serial bridge) or TUSB3210 (USB to GPIO interface) to enable an interface to the ADC of your choice.  Which TUSB device to use would depend on the ADC and the interfaces available on it.  In either case, FW would most likely need to be developed to enable the application on the TUSB device of choice.
