4.8.3 Right-Justified Timing
Right-justified (RJ) timing uses LRCLK to define when the data being transmitted is for the left channel and when
it is for the right channel. LRCLK is high for the left channel and low for the right channel. A bit clock running at
64 × Fs is used to clock in the data. The first bit of data appears on the data lines eight bit-clock periods (for
24-bit data) after LRCLK toggles. In RJ mode the LSB of data is always clocked by the last bit clock before
LRCLK transitions. The data is written MSB first and is valid on the rising edge of the bit clock. The TAS5508C
masks unused leading data bit positions.
