    Default question regarding an external AD converter

    I'm trying to interface a 12-bit AD converter(Gyropoint ASIC) with a PIC16F876, but I'm stuck.

    The instructions for the AD converter call for a 4Mhz clock. Thinking I could use my PIC and its 4Mhz crystal to provide the clocking, I connected the PIC OSC2 pin to the MSTR_CLK pin of the AD converter.. Is this okay? I suspect it is not since i'm getting nothing but a "0" reading when I display the data. While it may be that other portions of my code are causing the problems, I figure it's most likely this clock issue.... I'm pretty new at this stuff, so any help will be most appreciated.
    Thanks,
    Damian
