I2SE Interface DAC
Hi, Dear All,
I decided to build one high-end DAC with I2SE interface. Now I couldn't find the digital filter with I2SE input. Would u like to advice me? or tell me how to invert to I2S format.
BTW, the ICs on my hand now are PCM1704 and AD1896, PMD200.
If you can find a timing diagram for I2SE you can compare it to I2S and from there see what needs to be done. I would imagine the two are probably very similar judging by the names. The Assemblage DAC 3.1 has an I2SE interface maybe you can find a schematic of that.
You will need to bypass the AD1896 to get the PMD200 to work with HDCD as the AD1896 destroys the HDCD information.
Where did you get hold of the PMD200????
You can find the DAC 3.1 schematic at
but unfortunately without the PLL/VCO section ;).
Nevertheless, all you may need for I2Se implementation should be here, along with the specifications :
I would really like to know where you got hold of the PMD200??
Re: I2SE Interface DAC
My doughter board have following input
BCK (SCK in philips standard?)
LRC (WCK in philips standard?)
DIN (DATA in philips standard?)
SPDIF (yes! it is there)
and +5V and +9V and few grounds.
When I connected it like I mention in bracket, and add LC clock from SAA7345 (the same signal to board and servo) + SPDIF, then I received very low and disterted signal from DAC. vERY BIG AMOUNT OF DIGITAL NOISE TOO.
Would someone can help me to connect it properly to work as it should? Is it possible?
Thanks in advance
Oh no you can't find the schematic....... Check your links before posting people......
other docs on
http://www.partsconnection.on.ca seems out of business.
The link from ftorres :
(http://www.partsconnection.on.ca/pdf/dac-31.pdf) will not work. sorry to say.
Digital filters & I2S
The '1704 accepts it. Look at the board I designed.
Sorry for the bad link, but it was working when I posted it (January)....
