Left-Justified Mode
The audio interface of the TLV320DAC3120 can be put into left-justified mode by programming page 0 /
register 27, bits D7–D6 = 11. In left-justified mode, the MSB of the right channel is valid on the rising edge
of the bit clock following the falling edge of the word clock. Similarly, the MSB of the left channel is valid
on the rising edge of the bit clock following the rising edge of the word clock.
Figure 5-20. Timing Diagram for Left-Justified Mode
Figure 5-21. Timing Diagram for Left-Justified Mode With Offset = 1
Figure 5-22. Timing Diagram for Left-Justified Mode With Offset = 0 and Inverted Bit Clock
For left-justified mode, the number of bit clocks per frame should be greater than or equal to twice the
programmed word length of the data. Also, the programmed offset value should be less than the number
of bit clocks per frame by at least the programmed word length of the data.
