"Hi Guys,
A Long overdue update – Thank you to those who contacted Renata suggesting an update is long overdue.
I’ll be back in the Czech Rep next week for a couple of days and will be able to directly access my FB account once again and will reply to your questions as best I can.
I’m often asked about the units’ cost (as we head towards harder times) the modularity of the design allows a vast spread in cost – based on the DAC / Modulator / Analogue stage / Clock stages / Expansion modules fitted.
Apart from the Clock modules, the DAC can be user upgraded at any time as funds / new options allow. I’m sure I can also offer an exchange module discount and then offer these “used” modules for sale at reduced cost.
Some of the Clock / expansion modules are very specialized and only exist as they were part of the development process – or are used as components for future system development – the DAC clock design offers state of the art performance and has larger spin-off applications outside of audio (such as radar systems reference clock source where ultra-low close in phase noise is critical).
The current chip crisis seems to be going from bad to worst – so the modular design allows flexibility during build – FPGA / MCUs are especially hard to source – we have an official delivery quote from ST for a MCU for 2029 – reduced to 2028 when we pushed – this quote will be framed in the office!!! For development I’m purchasing parts from the spot market but at crazy cost and also a lot of duff, remarked and “recycled parts” it’s truly crazy times.
To optimise and finalize the DAC’s core clock technology, 5 months ago I ordered a MicroSemi 53100A Phase noise analyser – with an expected 20th August delivery date – I spoke with the T&M distributor last week to confirm the approaching delivery date – they said we would be lucky if it arrives on the 20th as the last unit they sold was delivered over 6 months late (so 1 year from order)."
There were also three images which provide a lot of detail about the various components. I've tried to link them a couple of ways, but not sure that I'm having any joy:
Clock,
DAC,
FPGA
