When using a Philips decoder, we have to delay serial DATA by another 7 or 11 BCK cycles (24bit or 20bit DAC IC). LRCK can directly be used as LE.
When using a Sony decoder, we have to delay LRCK instead of DATA. LRCK must be delayed by 8 or 4 BCK cycles (24bit or 20bit DAC IC). LRCK must be inverted and can then be used as LE.
Solution II: Instead of shifting LRCK, serial DATA can be delayed by another 20 or 16 BCK cycles (20bit or 24bit DAC IC). By doing so, LRCK can directly be used as LE.
There are of course further possibilities. Other formats from different input receivers or combinations with 18bit converters. Just look closely at the datasheets and figure out what has to be shifted and what must be inverted. If youve done that youre almost there.
แนวทางคำตอบ
The question now is how to implement this. To create a shifter, all you need are three different logic modules
The datasheets will help you understand how the explanatory circuit below works. If youve got that, just expand this circuit to get the right amount of shifting and correct LE.
