Re: [lpc2000] Strange problem with PLL

According to User Manual, you use lowest possible crystal, but it may works. Do you set CCO within recommended range 156 to 320MHz? For desired frequency 50MHz you must output divider adjust to 4 to keep this CCO range.

  Hello!

  I am working in a LPC2106, using a 10MHz crystal. I configure PLL to work at 
  50MHz. Sometimes the PLL locks, but sometimes dont. I cant see any difference 
  between the circuit when it locks and when it does not locks.

  Somebody had problems with PLL? Or maybe I have a malfunctioning chip?
