Not Subject to NDA
Sample rates of 8 kHz and 16 kHz
I2S
Master mode
Sample rate 8KHz, 16KHz
Sample-width is 16bit only.
Supported I2S standard only - Phillips I2S Bus Specifications revised June 5, 1996
In addition to the DVI port, the LE910Cx module provides a master clock signal (REF_CLK
on Pin B12) which can either provide a reference clock to an external codec or form an
PCM/I2S interface together with the DVI port where the REF_CLK acts as the MCLK.
The REF_CLK default frequency is 12.288 MHz.
When using the DVI with REF_CLK as PCM/I2S interface, 12.288 MHz is 256 x fs (where fs
= 48 kHz)
