Using PWM output as clock source
2006-01-05 by c_hall2001
I was designing a board with an LPC2138 and 2 ADC's. The ADC's require a 27Mhz clock. Is there any problem with using one of the PWM outputs to supply this clock? Do the LCP outputs provide a clean enough output at this speed to work like an oscillator? It would save some board space but I wasn't sure if there was a downside. TIA
