There is one more left if you wish to order now. After this lead time is again 4-6wks
I would like to place order for NDK. How do I do that? Please PM.

I see. Any reason not to use pn CCHD-950-25-100.000?

Default listening test of 90/98MHz VS 100MHz clock on ES9018?

Hi,,

Has anybody been making a listening test of the 90/98MHz Clock combination VS the 100MHz clock input on the ES9018 / Amanero ?

I like the theory of running even harm Clocks, which properly makes the ES9018 to sound better as the phase noise level of the clocks lowers when divided with 2 or 4 instead of having the PLL converting the 100MHz to usable sound format clock frequencies like 22,xxx and 24,xxx MHz rtc..

Please publish with links or comments..

Hi,
is it that easy? PLL vs. frequency division? By what? Digital or mixing?
I do not believe...
Cheers

Hi,

Sorry i needed to also state that the I2S and the DAC will run in "sync mode" when using 90/98MHz.

Assembly is nearly complete.

In the case of a single 100MHz XO, how do I handle R3 and R4? Any other things to do differently?

I have an early S03 board and an early Amanero. Presumably I should still follow your pdf pg5 modification notes?

For Async reclocking as above:
X2 - 100MHz CCHD-950 XO
R3, R4 - NC
X1- NC

Also, if not mounted already:
U8, U5 and associated components like C16, C17, C13, FB4, R13 not needed
FB1 and C7 not needed

Perfect - thank you!

I have all the "extra" components mounted, so I will leave them in place for now.

Should I also disconnect 'CLK' to Amanero pin #7, and link pin #3 of U8 to Amanero pin #6 at this point, while access is easy?

Leave both pin#7 and Pin#6 of Amanero unconnected and not need to link pin3,U8. For this application Amanero does not require external clock (Master Mode) and DSDOE is not used for any signalling.
