    Hi Andrew

    I think My Driscol oscilator fail

    On the reply 2110, I happy to say that, My system work.

    But it work for just 2 day, on the third Day, after I on and off the power of the system (include clock). the Clock stop working again , My FIFO LITE can not detect 44.1 Mhz. I try lots of time, but, can not detect.

    I borrow another clock (Driscol  22 and 24 Mhz from emyeuoi (Enrico, his on this post also) , my system detect very fast, and it sing again

    may be the problem: “” .6448 MHz and 6.144 MHz crystals have very high Q (more than 2M) and high ESR. With some
    crystals the oscillator needs long time to start and sometimes it doesn’t even start. In this case you
    can replace R24 (1K) with 1.2K, 1.5K or 1.8K resistor so it will start faster.””

    any Idea ?

    Tks
