DAC interface: OXUF922 (firewire 800 & USB 2.0)
This is where I found about it: http://www.1394ta.org/Press/2003Pres...hite_paper.pdf
, especially pages 4-5.
has both 1394b and USB interface. The serial audio interface is detailed on page 55. They avoid the magic word i2s
, (licensing issues?) but the interface seems identical. Also, one can configure the receiver (i.e. DAC) to be the master clock, so it should be ideal for non-oversampling DACs...
Furthermore, the chip has ATA100 interface, and can also used for 1394b ATA hard drive enclosures! I smell mass production here. Right now the price of firewire 800 stuff is quite high. It should come down in price when market share increases.
I have wet dreams of modding my next external HDD enclosure with a DAC...
Joke aside, please comment whether this seems a good DYI idea or not.
I posted the same message on head-fi dyi, but it seems that forum is not hardcore enough to elicit any responses
