OLM #3
OLM #3 serial audio interface format operates in Single-, Double-, or Quad-Speed Mode and will slave to
SCLK at 256 Fs. Eight channels of MSB first 20-bit PCM data are input on SDIN1.
OLM #4
OLM #4 serial audio interface format operates in Single-, Double-, or Quad-Speed Mode and will slave to
SCLK at 256 Fs. Eight channels of MSB first 24-bit PCM data are input on SDIN1.
TDM
The TDM serial audio interface format operates in Single-, Double-, or Quad-Speed Mode and will slave
to SCLK at 256 Fs. Data is received most significant bit first on the first SCLK after an LRCK transition
and is valid on the rising edge of SCLK. LRCK identifies the start of a new frame and is equal to the sample
rate, Fs. LRCK is sampled as valid on the rising SCLK edge preceding the most significant bit of the first
data sample and must be held valid for one SCLK period. Each time slot is 32 bits wide, with the valid data
sample left justified within the time slot with the remaining bits being zero padded.
