Product data sheet
8.2.2 I
The TDA9984A is able to recover the original clock from the S/PDIF signal (no need of
external clock). In addition, it can also use an external clock to decode the S/PDIF signal.
There are 4
carrying eight uncompressed audio channels. The I
I
formats are supported and can be selected by setting the appropriate bits of the register.
Typical waveforms for the I
The I
input with a clock frequency of at least 32 times the input sample frequency f
samples with a precision better than 24 bits are truncated to 24-bit format.
