OLM #1
OLM #1 serial audio interface format operates in Single-, Double-, or Quad-Speed Mode and will slave to
SCLK at 128 Fs. Six channels of MSB first 20-bit PCM data are input on SDIN1. The last two channels
are input on SDIN4.
OLM #2
OLM #2 serial audio interface format operates in Single-, Double-, or Quad-Speed Mode and will slave to
SCLK at 256 Fs. Six channels of MSB first 24-bit PCM data are input on SDIN1. The last two channels
are input on SDIN4.
