Any one also interested in 6mHz AT-cut? I am in for one and hopefully the MPQ can be reached.

I added another document (part VII) that explains how to connect oscillators, frequency doublers and sine to square converters to Ian's FifoPi.

There are 2 options to feed the FifoPi with 22.5792 and 24.576 MHz.

The first is:
- TWTMC-DRIXO 22.5792 MHz
- TWTMC-DRIXO 24.576 MHz
- TWTMC-STS-SX
- TWTMC-STS-DX
- TWRPS-UGL

The second is:
- TWTMC-DRIXO 5.6448 MHz
- TWTMC-DBM 5.6448 Mhz to 11.2896 MHz
- TWTMC-DBM 11.2896 Mhz to 22.5792 MHz
- TWTMC-DRIXO 6.144 MHz
- TWTMC-DBM 6.144 Mhz to 12.288 MHz
- TWTMC-DBM 12.288 Mhz to 24.576 MHz
- TWTMC-STS-SX
- TWTMC-STS-DX
- 2 x TWRPS-UGL

Thank you as much clearer!

1. What max music sample rate will this support?
2. In your view which one is the best solution?

Thanks!

andrea_mori · 2020-11-04 5:41 pm

I'm not sure because I don't own the FifoPi, but from the manual it looks like that with 22/24 MHz master clock it supports 176/192 kHz and DSD526.
Maybe someone expert in Ian's devices can confirm that.

The best solution in term of phase noise is the second but it's more expensive than the first.

SimonJ · 2020-11-04 5:52 pm

Thanks Andrea and I will read the manuals more. Appreciate your time.

Hi,
Excel form sent.
No crystal as I have one SC I need and ATs from previous GBs.

Many thanks again for all that awesome work and nice sharing.

cheers

cable type

I am thinking of using RG174 cable instead of the RG400 as this is much more flexible and usable.
The impedance is higher but I assume this will not impose a problem with the lengths we will be using in audio. I will not need more than 50cm of length.

Or is there a reason to go for the RG400 type that I have missed?

RG178 - Knowledge about coaxial cablesKnowledge about coaxial cables

The angled SMA connector is also more handy than the straight version.

any one also interested in 6mHz AT-cut? I am in for one and hopefully the MPQ can be reached.

I will also order AT 6 MHz, I will spread some info on the group buy at the computeraudiophile forum too..

Supersurfer · 2020-11-04 8:44 pm

The LMR195 is also a 5mm thick cable like the RG400.

The low loss does not have a lot of advantage when using less than 1m of cable.
I would guess the losses of the connectors are higher than a short piece of RG174 cable.

Yes, I ship from Italy (UE).

No custom, but I have to add 22% VAT for EU customers without a valid EU VAT Id.

22% VAT geee, live within the EU (Canaries) and pay local 9% or no VAT for SW/electronics..

I am thinking of using RG174 cable instead of the RG400 as this is much more flexible and usable.
The impedance is higher but I assume this will not impose a problem with the lengths we will be using in audio. I will not need more than 50cm of length.

Or is there a reason to go for the RG400 type that I have missed?

RG178 - Knowledge about coaxial cablesKnowledge about coaxial cables

The angled SMA connector is also more handy than the straight version.

RG400 is double shielding and lower capacitance.

I'm sorry, EU law, in Italy VAT is 22%.
But if you are a company with a valid EU VAT ID there is no VAT.
