+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.
