Part Number: PGA900

Hi,


does anybody know a website or document which explains the bit timming of the OWI Interface?

I can´t find this in the data sheet of the PGA900.

  • Hi Mario,

    The OWI bit timing on the PGA900 is going to be based on the baud rate setting you have the device configured to.  Are you having trouble communicating with your device?

    Hi Tom,

    i need a diagram which contains a descrption of the OWI data stream e.g. transmitting a logic 0 or 1.

    A example for the Bit timing based of the baudrate will be also very helpful.

    Regards
    Mario

    Hi Mario,

    Sorry for the delay here.  Figures 31 through 34 show the basic transmission of data through the OWI.  In the command and data fields shown, there can be any combination of 0's or 1's in the transmitted packet.

    Hi Tom,

    thanks the response.

    Do you mean the figures in the datasheet of the pga900?

    Regards

    Hi Mario,

    Yes, the figures in the PGA900 datasheet.  There is also a UART timing diagram in our ADS122U04 datasheet with a little more detail that might interest you.  You can find that in figure 1 here:

    Hi,

    thanks for the quick response.

    I'm afraid you misunderstood me. I´m looking for a more detailed description, like the picture below (Wikipedia screenshot).

    Hi Mario,

    Your picture did not come through.
