S and TDM mode and can

run at sample rates of 48, 96, or 192 kHz. The other two codecs are con-

operate in dual line TDM mode for 24 analog channels out and 12 analog
channels in at a sample rate of 192 kHz.

The audio input and output is available via multiple RCA connectors. A
group of switches is available if a user should decide to evaluate the audio
codec inputs and outputs in a differential mode.
