Integrated Inter-IC Sound (I2S) Component Maximum Speed – KBA90609
What is the maximum speed supported by the I2S component in PSoC® 3 and PSoC 5LP devices?
The I2S component supports a 64-bit word length, 96-kHz sampling rate with both Tx and Rx directions simultaneously. If a 192-kHz sampling rate (with 64-bit word length) is used, then only a Tx path or only an Rx path is supported.
Note: These are I2S component specifications. If you are doing USB audio, then USB full-speed bandwidth (12 Mbps) limits the maximum sampling rate to 96 kHz with 24-bit resolution (only audio-in or only audio-out direction).
