Question: Can the Cypress® digital audio solution support a 96 kHz sample rate using PSoC® 3 or PSoC 5LP?
Yes, the Cypress digital audio solution can support a 96 kHz audio sample rate. Below are the sample rates supported by the Cypress digital audio solution at both 16-bit and 24-bit resolution.
- 32 kHz
- 44.1 kHz
- 48 kHz
- 88.2 kHz
- 96 kHz (stereo audio-in or stereo audio-out only)
PSoC 3 and PSoC 5LP are USB full-speed devices. The bandwidth of USB full-speed devices (12 Mbps) limits the sampling rate to 96 kHz in only one direction; either stereo audio-in or stereo audio-out. A 192 kHz sampling rate is not possible.
The CY8CKIT-033A kit example projects only support up to 48 kHz stereo (in both audio-in and audio-out). If your design needs 96 kHz stereo support, contact email@example.com.
