Product data sheet
The I
input with a clock frequency of at least 32 times the input sample frequency f
Audio samples with a precision better than 24-bit are truncated to 24-bit. If the input clock
has a frequency of 32f
LSBs will be set to 0. If the input clock has a frequency of 64f
Philips, the audio word is truncated to 24-bit format and other bits padded with zeros. If
the input clock has a frequency of 64f
24-bit length.
The serial data signal carries the serial baseband audio data, sample by sample left/right
interleaved.
The word select signal indicates whether left or right channel information is transferred
over the serial data line.
