Asynchronous I2S FIFO project, an ultimate weapon to fight the jitter

Hi Ian

Just silly me....
I will not try to be that "smart" again....

Hi Rosendorfer, please keep your good job, no need worry about the board, I can fix it anyway .

If it is possible, try this one, TPS7A4700, it's the best low noise LDO so far. glt also recomended on his website.

If one wants to send clock signal to two DAC boards and to the source, that is already three, plus one to S/PDIF board, that is four. I do not know what is the effect on jitter, I am sure it does add some, but it seems that our contemporary systems will dramatically benefit if your clock is feeding all of the units. In the ideal system, in my mind, all units will work in a synchronous mode to your Big Ben . Would love to have your opinion.
Also, I am assuming / hoping to see a group buy for new units - battery management board, isolation board and new clock board. I will patiently wait.

Hi AR2,

You will have three u.fl MCLK output sockets from the new Si570 clock board. All of them come from a dedicate clock fan out buffer with only 29fs additive jitter. Furthermore, there will be three additional u.fl socket footprints for another group of I2S signals, which will work for your dual mono setup .

Si570 is the best solution so far I could touch to drive the ESS9018 DAC at sync mode with frequencies up to 90.xxx and 98.xxx MHz. I have been running the new designed 570 clock board for a whole week. I know CCHD957 is 4dB better at close in phase noise(@100Hz), but I almost couldn't come back to CCHD957 45.xxx and 49.xxx MHz on my system. (will share the result later on)

I'm not sure if I have chance running a GB for the Si570 clock board. It will be up to how many people are interested in it. Si570 will be very expensive if purchases quantity below 50 (I'm using free samples now). I noticed some people predicted Si570 is not suitable for digital audio applications. I pay respect to their point. Just feel a little bit unfair, they even didn’t ever try it.

Shall we start a list showing our interest in the Si570 clock board?

Thank bigpandahk, glad you are interested in the Si570 clock board. I'd like to give a try, you can put your name on the list now. I'll try my best to make the the GB running.

I have also put an index in the Si570 thread refering to the posts that are most relevant to demonstrating Ian's development of this device, hopefully this lets people avoid need to ask questions that already have answers buried in this thread.
