    Hi all,

    A simple 555 timer will work great for me though it only goes to around
    2mhz, does anyone know of a much faster chip or know if its possible to
    construct a circuit to double the frequency up ? I need it variable from
    100khz upto 10mhz or so, im using switches to alter the caps and resistors
    for the 555 at the moment which works great.

    thanks
    chris
