Hi Fabian,

order received, I'm still collecting order to reach the minimum quantity.

Updated Order Form

The last published order form was incomplete, this is the correct one.

 

[miksi]

At the moment this is only an interest list, we have to meet the MOQ to place the order to Laptech: 15 pcs for each frequency (5/6 MHz).

So I can delete the 49MHz Sc-cut Crystal (in stock at Laptech) from your order, but I cannot guarantee you will get the 6.144 MHz until we will reach the MOQ.

Please, let me know.

I thought that for this GB it's only necessary to reach MOQ (30-35 pcs) for the total number of oscillators regarding Laptech stock.

Yes, this GB is for Laptech stock, but if in the meantime we will meet the MOQ for SC-cut 5/6 MHz they will be added to the new order.

At this time I have collected order for 25 pcs of the Laptech stock, so I'm still collecting order to reach the minimum quantity.

Laptech stock update - closing the GB

Hi all,

the GB for crystals in stock at Laptech will be closed within the end of next week.

I will start soon collecting payments via Paypal.

If someone is still interested, please send me the order form as soon as possible.

We have not met the MOQ for 5/6 MHz SC-cut crystals, so the new order to Laptech does not include these crystals. The interest list is still open for a future GB.

[gerhard]

how do I get one for 100Mhz for DAC?

I'm also interested in 100 MHz, either AT or SC or both. Should be a standard product.
(for interest list)

 

[gerhard]

Theoretically at least 6 dB every time you divide by 2.
Practically I believe 5-6 MHz SC-Cut will perform much better, since the unloaded Q is closed to the highest you can get from a Crystal.

No, no. You get 6 dB maximum for dividing, and loose more than 6 dB
for doubling. Everything turns out to your disadvantage.

But the difference can be small.

Andrea,

I have just sent you the excel for the SC-Cut oscillator that I want, hope it is not too late.

I did not receive any paypal bill from you for my 5.6 Mhz oscyllator. Are you finally ordering them ?

Hi Pepe,

unfortunately the MOQ for SC-Cut 5/6 MHz crystals was not met, so the interest list is still open for a new batch.

I only have placed the order for Laptech's stock crystals because several members are waiting for a long time.

Andrea

 

[lindamar]

Thank you Andra

I am very sorry to hear we were not enough people to reach the minimum quantity required. My On my opinion those 5/6 Mhz are so good that you need to have them in your box for future projects. I really hope we can make it soon.

best regards and thank you again for your great work

Pepe

Is it better to use sc-cut 5.6M and multiplier to 22M than using 22M directly?

With a multiplier you loose at least 6dB (in real world more than 6dB), I would use 22MHz directly.
