Because my Reference TDA1541A DAC project has an I2S input, i need an additional I2S input converter.
For my iMac i use the Teralink X2 USB to I2S converter.
If you are interested in the device, look here on the Teradak webside:

This device needs no separate driver an could handle up to 96KHz/24Bit. The basic circuit based on the Tenor T7022L chip and has some major tweaking possibilities
1st the two voltage lines (+5V & +3.3V) 2nd the clock 3rd the I2S buffer IC
