McBSP to Quad SPDIF

Hi,

I'm in the brainstorm phase of designing a quad SPDIF output board for
the XM.

I require 4 spdif ports carrying stereo pairs of PCM data upto 192khz/
24-bit. Is that possible with the XM McBSP outputs in DIT mode?

Or should I consider connecting and writing drivers for something like
the AK4104A dev board?

TIA.
