R8 should have been 47K and not 20R as indicated earlier


There is an new update for download for registered users. Please use the link given before or here .
Changes:
1. Schematic corrected for CKSEL resistors
2. BOM updated for R5,R6,R8
Registered users of Clock Board AKX302 only

Not sure if there are any but comparable to Si570
For 45.xxx/49.xxx I think the CCHD597 has the edge over both Si570/590

If I tacked on the clock board to the this board how much would the power requirement go up to? The clock uses 5v as well, right?

From looking at the Subbu v3 board... ES9023 / WM8804 S/PDIF "Subbu DAC V3" GB Interest

Looks like there most likely isn't a MCLK U.FL pad there to use. Does this mean Async only?

Power requirement of the clock board is dependent on your PSU choice and XO choice, each will differ, the design is flexible and will vary depend on choices that you make.

Yes, it looks like Subbu v3 PCB doesn't have provision for external MCLK.

I was planning on using the Sigma 25 to power both the clock board and the re-clocker with 5v. I know that the re-clocker needs >100mA. I'd just need to be able to figure out how much the clock board is going to need to determine how much current my supply needs to be providing. My goal is to try isolation with re-clocking - sync mode (pg. 3) on the App Notes.pdf. So it looks like I don't need dual clocks. Is this possible with the AKX302 XO module to just use one clock? Would a datasheet provide the current needs of a particular 49.152 XO?

This is all going into curryman's v2 9023 board that "does" allow for ext. MCLK. Now that I know the Subbu v3 doesn't have that ability, I'll stick with Amanero > Isolation > Subbu v3 to compare Async vs. Sync.

Off the top of my head I would expect Isol+FF+XO+Clock driver IC + Clock divider FF to all still be less than 100mA. XO datasheet will tell you the load, max load for CCHD957 is 25mA.

The CKSEL can be configured in one position and use one XO only on the AKX302. This is how I will use it with at least one of mine. I'll be using AKD23 for my DACs

Each of the components have data sheets that will indicate their power needs, won't be hard to work out that.

Only one XO (X1) needed on the AKX302 board and output goes to RCK of AKL-AMN board. No CLSEL cct/connection or divider sections required. The re-clocked MCLK (22.xxx/24.xx) output from AKL-AMN goes to MCLK input of DAC The 49.xxx type for X1 (RCK) will do but higher ones with low jitter preferable as this is actually async wrt transport MCK causing modulation error. The higher the RCK freq the smaller the error.

You will see that the Sync mode is better. More details and soundstage!

Anybody tried the full sync mode, and have desoldered the XO's and everything needed from the amanero?
