Hi Team,

My customer care about the clock tolerance of MCLK, they use 24.576MHz as MCLK, they need to know what's the minimum and maximum value at here, thanks.

best Regards.

Wiky,

If the MCLK varies wildly the AOSR will also vary, which is not desirable. Most Crystals have a frequency tolerance less than 30ppm and stability less than 50ppm. this is not a problem for the PCM1862.

best regards,
