Gowin USB Audio Class
USB Audio Class (UAC) is an interface defined under the USB specification to implement audio device definition and control function.
Gowin USB Audio Class IP, based on the USB protocol, implements audio device functions. This IP can support up to 3 audio output devices and 3 audio input devices, controlling their sampling frequency, bit depth, and supported audio protocols. One end of the IP is a parallel data interface connected to the USB Device Controller, and the other end is an audio data interface linked to audio devices supporting protocols such as IIS/PCM based on user options.
- Supports high-speed and full-speed modes.
- Supports up to 3 input and 3 output audio devices.
- Supports synchronous data synchronization mode and asynchronous data synchronization mode.
- Selectable bit depth for each device: 16 bits, 24 bits, or 32 bits.
- Selectable sampling frequency for each device: 32kHz, 48kHz, 96kHz, 192kHz, 384kHz, or 768kHz.
- Supports IIS/PCM protocol interfaces and PCM data format.
