    Q:

    I would like to use the OMAPL138 EVM and interface to the uPP on it andI have several questions:

    1. Can I connect an external A/D to the uPP+clk at 60MSPS@10b ?

    2. Does the uPP currently interface to the ADS901 A/D ? 

    3. Are the uPP lines shared with other devices on the board ?

    A: 

    1. Yes the uPP supports 8 and 16 bit widths and with an I/O clock of 75MHz SDR can do 75Mw/s. The I/O clock has an upper bound of 1/4 the CPU clock.

    2. Yes, the uPP can be used to interface to A/D converters

    3. uPP_CH1 can be accessed through J29 and is not shared with other devices.

    Thanks a lot,

    Regarding question 2, how does the ADS901 A/D on the EVM board interface the OMAP?, Is it through the uPP?

    Thanks,
    Yuval
