My crystals landed.Their lead time used to be 6-8 weeks so I hope you're not in too big of a hurry.

Can't wait to see these new projects, that is the new R2R DAC and everything else.
Keep up the amazing work you're doing! 🙂

Do you really think it's a "extremely low phase noise crystal oscillator"?
It's not.
The Well Tempered Master Clock - Building a low phase noise/jitter crystal oscillator
You remind me that AS318B must be more competitive, so the price of 45 and 49MHz is directly cut in half now, only 20 US dollars, including international postage fee.

All those clock buffer chips are for telecom applications and they completely ignore the
noise outside 12KHz-20MHz to arrive at their wonderful specs.....
The chips may be OK, but that must be verified.
Gerhard,
Datasheet Figs. 10~13 goes down to 1kHz.
And I also like the York design.
😉
Cheers,
Patrick

I have never talk about price, since you claimed that the Accusilon is a "extremely low phase noise crystal oscillator" I did remind you to the plots and measurements of some real low phase noise oscillators, so you can see that the Accusilon is a "extremely HIGH phase noise crystal oscillator".

You bought a moq at Laptech ? 😕.... big needs 😀 !
Ah, you came in between ?!
What I meant is indeed Laptech takes a little times and Andrea (and now the "We" team) are ready before on the pcbs printing & shippment. My question was more related about you had to buy a moq and perhaps didn't need all. So As I have only three at-Cut and only a 5 Mhz SC-Cut I will ask if I need an SC-Cut before the next grup buys but if you populated all of them already 😎. My SC-Cut is agging between two Bordeaux and few Bourgognes bottles in the basement - SC-Cut 2019 edition-
Why they created 2 speeds, is it not strange they did ?!

DRIXO, EXO and PXO require transformers kit.
Hi,
I haven't paid attention to this thread in a long time. I found out that a new oscillator has been developped?
Is the design public or only available through the groupbuy?
If it's public, is there a document with schematic/PCB/BoM and possible requirements? Where can I find it?
I noticed you are doing a battery supply nowadays, sounds great!
The BOM and the assembly instructions of each device will be published in this thread as soon as we have ended test and tuning.

Sounds awesome. Thanks for the quick reply and sharing your design. You're making many audiphiles happy 🙂

I think I was lucky, nothing else.There was not enough interest for the frequency of 16.9344MHz even in the previous GB. So I decided not to wait, but to order.The fact that it was accidentally available in stock
from some previous production, certainly helped.
I am definitely on your list Andrea. Will wait for until you finish your tests.
I am also interessted in this GB, but I wait for information of the tests and if the new FIFO also can be ordered in this GB
And schematic.

YESYesyes!!!11!
This thread is about designing oscillators and not really about soldering
a kit.
I should ask Laptech, anyway at least a MOQ of 10/15 pcs.
BTW, if you are looking to reclock the Raspberry it's not worth, you will not get any improvement.
The only way to improve the jittery I2S coming from the Raspberry is isolating all the signals and then use a FIFO reclocker.

Andrea, this is not true. I use Terradak OCXO 0.01ppm, the reduction in jitter is incredible. I want more!
I cannot see any OCXO upgrade for the Raspberry on TeraDak website, I see only a board with a pair of cheap TCXO (Raspberry Pi 3B+ modified clock crystal TCXO warm-filled crystal oscillator upgrade crystal oscillator) without any phase noise measurement.
Can you point me to the OCXO you are talking about?
