The Well Tempered Master Clock - Building a low phase noise/jitter crystal oscillator

[deanoUK]

So the "new clock" is deployed on the Ian's MCFIFO ? Prior to I2S LVDS distribution ?

Make your imagination work, it should not be too difficult.

Right, if there was more detailed description.

I guess a room bigger than a living space,is almost 50-60 square meter.

I live in a compact 620 square foot 1 bedroom flat and was thinking volumetrically as the room in question is two stories tall so a 20’ * 30’ is close to 2 times my situation. Acoustically it opens to hallways and other rooms so the space is even bigger.

Yes the new clock replaced the clock in Ian’s MCFIFO so reclocking the MCstreamer.

Thanks. What DACs chips are fed ? Is MCLK is sent over LVDS ?

Apparently, you don't understand what listening room detail means.

I imagined a warehouse with a PA stack at one end !

Just finished my oven. I simply glued the PTC elements and regulator to the crystal with thermal glue and insulated them with a styrofoam housing.
Nice improvement

 

[wlowes]

Well done!

Hello Koala,
Is the '' bubble gum '' a soft material and will it keep its properties for a decade to come?
Once i used a similar looking material in a non audio application and a few months later it turned hard and brittle..
Probably when used in an almost airtight surrounding and no UV light properties wont change much.
Greetings, eduard

The chewing gum is Teroson RB IX. This is permanently elastic and I have been using it for vibration dampening for several years.
I can highly recommend it for the clockboard, it has a greater influence on the sound than e.g. the oven or power supply.
Just tap on the clock pcb and listen to the vibrations. Not a good environment for a quartz ...
A good alternative is to place the clock outside of the listening room.

Just in case Andrea wil organise another GB, I may be interested in a 10MHz Driscoll xtal. Andrea has informed me that the MOQ would be 10 pieces. Including mine and one other user's that I happen to know of, that would leave 8. Are there any users here that would be interested in this frequency?

 

[jrocker]

I’m interest in a group buy too, I just don’t have the impression that that is possible.

 

[Markw4]

Looks like we will just have to wait and see how things turn out. If there is some future group buy it may not be organized through here. For now if there is interest this may be an okay place to say so.

Indeed, that’s the idea behind my post.

I am interested

Why do you need Andrea if you only want crystals? Contact Laptech and get a quote then organize. They sell to private customers as well.

 

[kunlun121]

That is a reasonable comment. I’ll consider that.

Yep, for common frequencies like 10MHz the MOQ is 10pcs. Shipping is from Canada, but certainly it will be cheaper than adding a round trip to Italy. Quartz Crystals,OCXO, TCXO Precision Oscillators and Custom Wound Components by LapTech Precision

I'll let you discover the pricing, you may have a surprise .
