AIC3204 32.768KHz ref CLK

Other Parts Discussed in Thread: TLV320AIC3204

Hi, Do you think that is is possible to configure the AIC3204 from a 32.768 KHz crystal or from a 32.768 Osillator ? My target is codec master mode, 8Ksps, 16bits, stereo, BCLK=512 KHz (word length may also be 20,24,32). Thanks. Nicolas

    Hi Nicolas,

    The input clock minimum is 512kHz if not using the PLL fractional dividers and 10MHz if using the PLL dividers. Also, internal modulators need around 128*FS minimum and internal processing needs around that value as well (search RC, or resource class, in TLV320AIC3204 datasheet and application reference guide).

    Regards,
