Hi Guys ![:)]( "Smile :)")
I’m using the VS1003 chip from VLSI which is an MP3 decoder chip for micros.
I connected the example circuit from the data sheet as shown, and it uses a 12.288MHz crystal.
When first powered, I noticed a crackle from the earphones, and figured out the crystal was oscillating intermittently.
It was only when I made the cut in red that it fires up reliably. Can anyone tell me why this is?
Perhaps I should have used the 22pF caps I normally use for any crystal up to 25MHz,
but I was...
Crystal not Oscillating
