Hi guys
I'm in on this as well but can someone help me with my order please?
@Basillus, I think you have 3 or 4 Buffalo BS-GS2016 switches but I only have two (switches) that I want to upgrade; so, would I need to order the same parts as you:
2 x TWTMC-PXO-AIO with the AT 6.25MHz
2 x AIO XO transformer kits and
1 X TWTMC-STS-FSDO-F
or would I need something else?
Thanks
"2 x TWTMC-PXO-AIO with the AT 6.25MHz
2 x AIO XO transformer kits and
1 X TWTMC-STS-FSDO-F"
Why 2 x TWTMC-PXO-AIO and 2 x AIO XO transformer kits?
You have two switches, these requiring two 25Mhz clock:
One 25Mhz sine output board, and one sine to 2x square board.
1 x TWTMC-PXO-AIO with the AT 6.25MHz: 25MHz sine output
1 x AIO XO transformer kits and
1 X TWTMC-STS-FSDO-F : 2 x sine_to_2x_square (only one half needed)
2 x AIO XO transformer kits and
1 X TWTMC-STS-FSDO-F"

I would add saying that the transformer kits are needed for the semifinished (-SF) versions, but not for the finished (-F).
Yes, all the (-F) finished boards are fully assembled and tested except for the crystal and the box.
Thank you Andrea!
+1 for you Fifo lite
1 With your new FIFO Lite is there need for sine to square converters?
2 I see that you missed the measurements for the 12.288 DRIXO, at least i cannot find them.
3 I found measurements of some very good commercial products (Grimm CC and Black Lion). Looks interesting

1) No, the FIFO Lite has the sine to square converter on board.
2) I have not measured the DRIXO at 12.288 MHz because I don't own the crystal (never ordered in the previous GB).

Andrea, have you made any PN measurements for LE (WS/LRCK) based on your clocks? Or this measurement will be a part of the comming FIFO later? Thx.
Hi Ivan,
we will measure the LRCK of the new FIFO Lite with our oscillators as soon as it's ready.

Andrea, I'm planing to replace only one clock in a dac that has many clocks.
So need to receive an "on/off signal".
If using these three cards
Driscoll XO -> Frequency doubler -> Sine to Square converter
Is it possible to connect an on/off "trigger" without replacing Square converter with for example the switched output card (and only use one input)?
Or do you know if any pre-build solutions exist? Like "bnc -> on/off relay -> bnc", or something like that.
thanks Micke

Hi Micke,
oscillators and frequency doublers are always on, there is no way to put them in high impedance state.
So the only way is using the TWTMC-STS-FSDO-S that accepts on-off signal to switch between two oscillators (in your case one is empty).
Otherwise you should build yourself a switching board because commercial devices are expensive.
This is an example
https://www.mouser.it/ProductDetail/Teledyne-Relays/CCR-33S80-R?qs=YCa/AAYMW0112XqxgJXHlw==.
It's a latching device so you need the control logic to to switch between the oscillators, and moreover it uses a single relays while the TWTMC-STS-FSDO-S uses 4 relays, 2 for each input in T configuration.

Andrea, sorry if it was asked..what shortest lenght SMA cable is enough to connect stacked boxes of oscillator and doubler like shown in your manuals?
I suggest rfsupplier, you can get custom cables at affordable prices
