The NCO (Numerically Controlled Oscillator) block found on Apple SoCs
|
|
such as the t8103 (M1) is a programmable clock generator performing
|
|
fractional division of a high frequency input clock.
|
|
|
|
It carries a number of independent channels and is typically used for
|
|
generation of audio bitclocks.
