Yes. > Isn't AIC33 able to create common audio > frequencies internally from a reasonable input clock, say 27 Mhz? Some frequencies. To get others, it helps to have some choice of frequencies. The PLL1705 is fed by a 27 MHz oscillator ... that logic isn't integrated into the AIC33, but it *is* part of the PLL chip. _______________________________________________ Davinci-linux-open-source mailing list [email protected] http://linux.davincidsp.com/mailman/listinfo/davinci-linux-open-source
