Cheat sheet: sample rates and clock frequencies

I2S audio connections usually use 3 different clocks: a frame clock, a bit clock and a master clock that must be synchronized. This is just a small sheet showing different sample rates for the standard sample rates. One thing that is important for anybody designing I2S audio interconnects: The frequencies can be relatively high. Make sure, you keep the traces as short and use countermeasures against ringing. Otherwise your circuit might interfere other devices.

Sample rate 32xfs 64xfs 128xfs 256xfs 512xfs
44.1kHz 1.4112MHz 2.8224MHz 5.6448MHz 11.2896MHz 22.5792MHz
48kHz 1.536MHz 3.072MHz 6.144MHz 12.288MHz 24.576MHz
