6.5 I2S Mode Application
The IS2064GM and IS2064S/B SoC provide an I2S digital audio output interface to connect with the external codec or DSP. It provides 8, 16, 44.1, 48, 88.2 and 96 kHz sampling rates for 16-bit and 24-bit data formats. The I2S setting are configured by using the UI and DSP tools.
Note: The UI and DSP tools are available for
download from the Microchip website at www.microchip.com/wwwproducts/en/IS2062 and www.microchip.com/wwwproducts/en/IS2064.
The external codec or DSP interfaces with IS2062/64 over these pins: SCLK0, RFS0, DR0, and DT0. The following figures illustrate the I2S signal connection between the IS2064GM and IS2064S/B SoC and an external DSP. Use the DSP tool to configure the IS2064GM and IS2064S/B SoC as Master/Slave. For additional information on timing specifications, refer to Timing Specifications.
