Dclocking.rst2 Audio Clocking
5 This text describes the audio clocking terms in ASoC and digital audio in
6 general. Note: Audio clocking can be complex!
10 ------------
12 Every audio subsystem is driven by a master clock (sometimes referred to as MCLK
13 or SYSCLK). This audio master clock can be derived from a number of sources
14 (e.g. crystal, PLL, CPU clock) and is responsible for producing the correct
15 audio playback and capture sample rates.
17 Some master clocks (e.g. PLLs and CPU based clocks) are configurable in that
