With regards ADAU1442
Hi ,
Could you please let me know know can we convert Leftjustified 16 bit audio data to IIS 16 bit Auto using the following setting .
Input Data
Serial Input setting
fs = 22.05kHz
Master/Slave = Slave
BCLK = 32fs
BCLK = Negative
LSB Justified 16bit
LRCLK = Negative
Master
WordLength = 16bit
LeftJustified(Delayed by 0)
Output Data
Serial Output setting
fs = 48kHz
Master/Slave = Master
BCLK = 64fs
BCLK = Negative
I2S 16bit
LRCLK = Negative
WordLength = 16bit
I2S(Delayed by 1)
Thanking you
With best regards and wishes

Hi,
As this relates to the ADAU1442, I have moved this discussion from the Processors and DSP community to the SigmaDSP Processors and Development Tools community. Please continue the discussion here.

Hello,
I want to make sure I understand the input format. You say that it's two channels, 16-bit, and 32 BCLK cycles per frame, correct? That means that there are no "padding" bits... i.e. all bits contain data. Is that correct?
In other words, the 32 BCLK cycles look like this:
... R15 L0 L1 L2 L3 L4 L5 L6 L7 L8 L9 L10 L11 L12 L13 L14 L15 R0 R1 R2 R3 R4 R5 R6 R7 R8 R9 R10 R11 R12 R13 R14 R15 L0...
Is that correct?
If so, then unfortunately the ADAU1442 will probably not be able to handle this data. It expects at 32 BCLK cycles per channel, which would make for a total of 64 BCLK cycles for 2-channel data.
