In I2S interface in stereo mode, each stereo sample consists of two channels, each with a 16-bit data depth.
Therefore, the total bit depth for one stereo sample is 16 bits/channel * 2 channels = 32 bits.
The sampling frequency is 44.1 kHz, meaning there are 44,100 samples taken per second.
To determine the bit clock frequency (fbsck), we can use the formula:
fbsck = sampling frequency * total bit depth
fbsck = 44,100 Hz * 32 bits
fbsck = 1,411,200 Hz
Therefore, the bit clock frequency of the I2S interface configured in two-channel (stereo) mode with a 16-bit data depth and a sampling frequency of 44.1 kHz is 1.4112 MHz.
