S/PDIF Transmitter
Serial data input to the S/PDIF transmitter can be formatted as
left justified, I
or 24 bits. The following sections provide timing for the
transmitter.

for the left channel and high for the right channel. Data is valid
on the rising edge of SCLK. The MSB is left-justified to an
LRCLK transition but with a single SCLK period delay.

left channel and low for the right channel. Data is valid on the
rising edge of SCLK. The MSB is left-justified to an LRCLK
transition with no MSB delay.

left channel and low for the right channel. Data is valid on the
rising edge of SCLK. The MSB is delayed 12-bit clock periods
(in 20-bit output mode) or 16-bit clock periods (in 16-bit output
mode) from an LRCLK transition, so that when there are 64
SCLK periods per LRCLK period, the LSB of the data is right-
justified to the next LRCLK transition.
