LPC 2294 clock circuit

Started by sowjanyaraju_ai October 24, 2009
hi friends, i hava a doubt what is capacitor value for the clock circuit for LPC 2294,i want to use 12Mhz crystal oscillator.In some cases i saw 22pF, and some cases i saw 38pF. which one is correct?

It depends on the crystal load capacitance. See the User Manual.
