if I want to switch from 12.000 Mhz crystal to say a Fox 3.3V TCXO [SMD]
which of the two TE7022 pins gets the CLOCK-OUT from the oscillator?
Pin 37? Pin 38?
Happy new year!

You must connect the osc. out to pin 37 (XI) of the TE7022L.

I have a TE7022/ES9023 HifimeDIY USB powered DAC now modified with Fox ~+/-2.5PPM 3.3V 12.000 Mhz SMD TCXO Oscillator! While I was in there I added a TPS79633 dedicated 3.3V regulator for the ES9023, that has a pin they ask that you filter: pin 5. I pre filtered the USB +5. I post-filtered the onboard 3.3V regulator, added the dedicated DAC regulator, and filtered that a little with SMD cap. I run this from a fiber-optic USB isolator Opticis m2-100-03 which is good to 12Mbps, just fine for the TE7022. I have 30 more Opticis isolators, if anyone needs one, PM ME.

Thanks for the information on the XI pin #37 on TE7022!! Happy New Year!
