Serial Audio Interface Control and Timing
3.7.1 I2S Timing
I2S timing uses an LRCLK to define when the data being transmitted is for the left channel and when it is for
the right channel. The LRCLK is low for the left channel and high for the right channel. A bit clock running at
64 × Fs is used to clock in the data. There is a delay of one bit clock from the time the LRCLK signal changes
state to the first bit of data on the data lines. The data is written MSB first and is valid on the rising edge of
bit clock. The TAS5518 masks unused trailing data bit positions.
