If using bus power only (no dedicated linear) then what voltages is the card using through the PCI express connection... 12v (stepped down internally by LT3045?), 3.3v or both? JCAT Website states "State-of-the-art LT3045 linear regulators and filters eliminate noise interferences from a PC" Would you be able to explain a little more about what filtering and noise reduction actually occurs at the PCI Express connection? If powering USB XE using an internal/external linear power supply, then is it true that the only source of electrically transmitted noise through to the USB XE will therefore be just the SMDAT/SMBus data collection pins? Do you know which voltage rail the SMDAT/SMBUS data tranmision pins are powered off? Thanks 1. 3.3V 2. The filtration and noise reduction is provided by the LDOs. You can see the exact specs here: https://www.analog.com/en/products/lt3045.html#product-overview 3. I don't know. But I can tell you that the PSU for the PC is still quite important and easily audible, if that was your question. As a matter of fact, we are in the process of designing a high-power version of a PSU for a PC. Regards, Marcin JPLAY & JCAT Founder Link to comment

Pablooo Posted July 2, 2020 Share Posted July 2, 2020 On 5/27/2020 at 12:30 PM, Marcin_gps said: NEXT BATCH UPDATE I'm afraid I have unfortunate news. I've just received an email from Digi-key regarding availability of the OCXO oscillator we use on the USB Card XE. The original shipping date when we placed the order was June, 6th. Now the date is June 30, 2020, with an additional, approximate 6 business days transit from the manufacturer to Digi-Key. The SiT5711 is popular and SiTime has not been able to get ahead of the demand. Regardless, we are pushing to get the oscillators sooner, but it seems that the USB Cards XE will not ship sooner than in July. I know this is disappointing, but there is very little we can do. I will keep you updated. On the bright side: Sorry I ordered already and canceled 3 days ago cause of my already great sounding server but I heard it at a friends server and it’s a musthave…. Best regards, Marcin Hi Marcin, Could you provide us with an updated delivery schedule of the XE card? Thanks! Link to comment

The current lead time information for the OCXO SIT5711AC-KW-33E-20.000000F-ND is that they are expected to arrive at Digi-Key on July 8, 2020. We have other components in stock, so the assembly will start shortly. Regards, Marcin JPLAY & JCAT Founder Link to comment

Thank you Hi William, The manufacturer of the OCXO (SiTime) delayed the delivery again from July 8 to July 30, but after a conference call with them we managed to expedite the delivery to this week. Once we receive the oscillators, we will start the assembly. Hopefully we will be ship the orders by the end of July. I wish I could give you better news, so you could enjoy the cards sooner.

Summit Posted August 13, 2020 Share Posted August 13, 2020 I have one question that I can’t figure out myself. Why are there no shield case on this and other TOTL audio cards that are meant to be placed inside a (noisy) computer? Link to comment

Pablooo Posted August 15, 2020 Share Posted August 15, 2020 From what I understand is that the oscillators were in backorder and this causes the delay of the delivery of the XE card. However, the oscillators were sent to Jcat 2 weeks ago so I figure the delivery of the XE card is about to take place. @Marcin_gps could you confirm a more precise dispatch date? Link to comment

Hi Pablooo, Yes, this is the case. We received the oscillators and we're assembling the cards. Once the batch is ready and tested, the cards will be shipped from the factory to our place. If everything goes smooth, all backorders should be dispatched within 2 weeks. Best regards, Marcin Ostapowicz JPLAY & JCAT Founder JPLAY & JCAT Founder Link to comment
