When I commissioned the factory to manufacture the DSD'it SRC4192+AK4137 board, I encountered some troubles. They said they couldn't understand which of these two inductors should be purchased, so the current manufacturing process has stopped, so I need to know the specific values of these two inductors. thank

I use iancanada's reclock for two reasons. Firstly, I have a pair of very high-quality pulsar clock ocxo in pin 14 package, and the clock signal quality will directly affect the result of reclock.
Secondly, iancanada recently launched ReclockPi can further reduce jitter to 3.76ps by CCHD957.

Based on user reviews, the Chinese have designed compatible modules that are better than Amanero. USB????PCM1536 DSD1024??Amanero???XMOS?I2S????-???
I don't know the exact parameters. I use inductors 10µH 7.3x7.3 noname.
For clocks, you can also use for example: MLZ1608N100L TDK | Mouser
I initiated a group purchase for DSD it SRC4192+AK4137, if you are interested, you can join.

I found that the CT7302 / CT5302 made by ComTrue, a Taiwanese company, seems to be stronger in specifications than the AK4137, and the price of the CT7302 is about $20. CT7302 / CT5302 is integrate with SPDIF.
However, ct7302cl was launched very early, but it is still unknown. I don’t know why? It may be that the company’s product is only SRC, so that it is unknown.
Can CT7302 / CT5302 be integrated with src4192? Or is it compatible with two CT7302 / CT5302?

audiodesignguide3 has compared CT7302 and AK4137 using the instrument to. He found that CT7302 (0.0067%) is much better than AK4137 (0.01%).

IME, CT7302 sounds much worse than AK4137. We have already discussed this stuff in another forum thread.
Also, regarding the use of ferrites for cleaning clock power: Probably better to avoid them unless experiments show they are really necessary for a particular board design. IMHO only, I believe they can create hysteresis noise that leads to increased clock jitter.

I designed a conversion board between DSDit SRC board and Ian's STATIONPI, so that the I2S output of DSDit SRC board and beaglebone black can be passed DSD signal to Ian's reclock via STATIONPI.
sorry guys but I am not sure of understanding how this board works. Is it possible to use it with USB DAC? SPDIF? How?
I mean, stream is upsampled in the DSDit and DAC is connected to the BBB via USB....😕😕

Hi jmmbarco,
According to the original design of the DSDit SRC board, it is to provide the DSD signal required by the DSC dac. However, the conversion board I designed by myself can connect the I2S signal output by the DSDit SRC board to Ian's Reclock.
However, no matter what kind of DAC can accept I2S signals, of course it includes the I2S signals of the DSDit SRC board, but you need to find a way to correctly connect the I2S output of the DSDit SRC board and the I2S input of any DAC.
The purpose of the SRC board is to output high-quality DSD signals without requiring a powerful PC. According to the designer's experience, the DSD quality of the DSDit SRC board is similar to that of Roon.

Hi yunyun, thank you for the reply, but I would like to use this SRC with my second DAC which only accepts DSD128 via USB. Would it be possible?
Thanks again!
Thanks again!
In this case I must upsample in the PC (this is how I do in my main system using HQPe), but in the second setup I would prefer to upsample via hardware in the naa side and DAC connected via USB
I think I had confused two different things. Ak4137 SRC is I2S output only whereas Pure firmware offers USB and I2S output from BBB when loaded. So no USB output from SRC...
I should have read better.😱 Sorry and thanks!

Sorry for thread pollution ...
Is any of you are building the PureBone - SPDIF / AES for BeagleBone?
