Not necessary for single clock setup if XOs have internal pull ups for Enable lines. e.g. CCHD957, Si590
Synchronous Re-Clocker for Amanero
I am planning to roll out a new model by combining the Master Clock, Re-clocker and Isolator cct all onto a single board. It will specifically target the Amanero with FW update to take external clock (22.xx/24.xxMHz). Ref: App Notes, Full Sync mode. The external interconnects like RCK and CKSEL are now integrated on board with short traces and layout optimised. The Amanero unit will plug on board as shown to form an enhanced USB-I2S DSD transport

Not finalized yet, especially the dimensions. Of course trying to make it as compact as possible
Limited discounted offer + free shipping for current users and a free board each for those who helped with the testing and evaluation, thank you

One of the many reasons we all love you, acko

I was thinking about that too, because I haven't built up my AKX302, yet, then I realised that I can now build the AKX302 for a single clock freq and use the discrete boards for asynch reclocking and the revised board for synch re-clocking.
New board looks good Acko! I agree with bk856er, board size looks good and compact already and keeping physically away from the Amanero parts helps keep the sensitive part of circuit away from the noisy CPLD/. To go any smaller you'd be using quad FF and probably 4+ layer PCB to get all the signals in/out of the quad FF.
Agreed! I'm continually impressed by you productivity and work product. Then you add the occasional 'deal'.... Awesome work Acko!
hsi68: What kind of XO board is the T-clock you have?
The T-clock made by Korean DIY society recently. Actually, its purpose is supplying accurate clock to Alix 2d2/3d2 MPD board.
The T-clock has the following characteristics.
Ultra low Jitter, Zero PPM, and 4-ch programmable.
zero ppm hey? sorry ... that can only be marketing
OK its using something like Si5338, yes zero ppm seems to be more of a marketing term. it relates only to programmable frequency setting resolution, not jitter. its not clear if it even applies to any type of long term frequency accuracy, just the setting resolution
