OCXO ADUM3166 USB isolator

I just want to make this isolator with the best solutions I can use. In fact, OCXO, polymer tantalum capacitors, LT1963, SI5341 PLL, 4-layer PCB. Thanks to the fact that I'm in China, these don't cost too much indeed.

Yes, I understand. Maybe some people are used to the manufacturers' practices of saving materials. For example, using common X7R capacitors and 3225 crystal oscillators. But I don't think it's necessary to be that thrifty.

Yes, for Hi-Fi, it's better to use better ones.

Oh, wow, who would have thought? The really nice thing is you can use the same profound statement for ethernet too 🙂
It's a great coincidence that I also have a network switch using OCXO.

Looks like a great product! Would you have any specific recommendations for the power supply? I'd be a little hesitant to introduce a switching power supply, given that isolation is the whole point, but 9V/1.5A is going to be big and hot if using a linear supply. Any chance we can get away with less current?
 
@op111op Hello do you recommend any Ali store in specific we should buy your products through? I have bought the UAC-1 and RDAC-1 through your TaoBao store via a client but have been wondering what Store you recommend an NA buyer to buy through. I look forward to buying you new HP amplifier looks nice!
