You will have to tap the I2S lines going into the DAC chip and feed them into an SPDIF transmitter and coaxial output (which you need to design yourself and place on a seperate board). Looking at the datasheet for the DAC will help you in finding which lines need to be rerouted.

Oh, thank you for your reply. I try to check the datasheets of the follwing chips. but it is so hard for me to find I2S lines.

BCK, LRC, and DIN on the DAC chip are the I2S inputs. The chip has its own crystal to generate a clock signal, which might affect your SPDIF transmitter choices. However, I would recommend that you ask someone else on this forum for confirmation before you start tapping the lines (I've seen people here who have done this before).

SAA7327 Pin 51 DOBM. If it is active you have your spdif output.
