+title: StarFive JH7110 PWM-DAC Controller
|
|

|
|
+description:
|
|
+ The PWM-DAC Controller uses PWM square wave generators plus RC filters to
|
|
+ form a DAC for audio play in StarFive JH7110 SoC. This audio play controller
|
|
+ supports 16 bit audio format, up to 48K sampling frequency, up to left and
|
|
+ right dual channels.
