Andrea, I'm out. Can you take me off the list please?

Ok, done.

Update

The payment requests have been sent to all the members.

As soon as I received all payments I will place the new order to Laptech.

Hi andrea,

Payment sent. BTW, the board of Driscoll and oven will be on next GB? I didn't see them on the order form.

Yes, I have to get SC-cut crystals firstly, without them I cannot test the new Driscoll oscillator board.

Hi Andrea,

Payment sent. Could you add to my order 2 TWCMC-C XO boards?

Thanks,
Alex

Hi Andrea,

Have you tried the PO38072 1:2 clock buffer as sine-to-square wave converter? I found it has excellent performance. Could be a better alternative to 74hc04 logic.

I cannot find anything on the web about the PO38072, can you provide a link?

I suspect it's the potato semi: http://www.potatosemi.com/potatosemiweb/datasheet/PO74G38072A.pdf

Sorry, the correct name is PO74G38072A. Product page is here. If you like I can send you a sample.

The pot semi clock chips have the lowest pin to pin skew (jitter) I've found.

Hi ..

@jborden:

The pot semi clock chips have the lowest pin to pin skew (jitter) I've found.

Might you also have experience with the jitter level in their other IC's - like e.g. their PO74G74A flip-flops?

Cheers,

Jesper

Reminder

I would finalize the order to Laptech, so I ask the members who have not yet payed, please do it as soon as possible.

Thank you
Andrea

Last reminder

Miklos, Gunders,

you have a payment request for the Laptech GB.

Please, let me know if you will pay for the crystals. Otherwise I should cancel your orders to finalize my order to Laptech.

Thank you

Andrea

I've used them because of their reputation for low noise low jitter but don't have the equipment to measure levels that low

Andrea,
I see you don't have any 16.9344 Mhz for SC cut , is that right ?
