    CY68013 Clkout wrong

      I have a 24 MHz crystal oscillator attached to the XTAL_IN and XTAL_OUT of the CY68013 128 pin package.  The voltage level on the XTAIN_IN side is around 3.3 Volts peak-to-peak.  On the XTAL_OUT side I am only seeing 2V.  My CLKOUT pin then puts out around 140 MHz, which is WAY above the default of 12 MHz.  I see CLKOUT intially start at 12 MHz(default) then change to 140 MHz.  Why is this clock so fast?  Could the 2 Volts peak-to-peak be the issue?  Why am I only seeing 2V peak-to-peak?


      Thank You.
