2-Channel I
2S Timing
In 2-channel I2S timing, LRCLK is LOW when left-channel data is transmitted and HIGH when
right-channel data is transmitted. SCLK is a bit clock running at 64 × fS which clocks in each bit of 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 the bit clock. The
TAS3204 masks unused trailing data-bit positions.
