TAS5518
3.7.2 Left Justified
Left justified (LJ) 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 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 at the same time
the LRCLK toggles. The data is written MSB first and is valid on the rising edge of bit clock. The TAS5518
masks unused trailing data bit positions.
