Left-Justified Timing
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 48 or 64 times 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 the bit clock.
The TAS5026 masks unused trailing data bit positions. Master mode only supports a 64 times Fs bit clock.
