Hi all,
I’m working on building a clock board for my CD player at the moment. At the minute it’s got one of those inexpensive boards from eBay on there which works very well: 15MHZ TCXO 0.1ppm Ultra precision Crystal Oscillator CLOCK+PSU board | eBay
But of course - always room for improvement especially with very low cost parts 😀
The board alone sells for about £3 and the crystals seem to sell for about £15. The sellers claim very low jitter on the crystals (one of them I can’t find now posting an alleged comparison graph with a Tent XO and coming out very similar)
Does anyone have any experience using these cheap TCXOs for me to reuse on a new board, and are they as good as they claim or would something like a Tent XO give better performance?

Go for an AT-cut crystal and use ECL circuit if you want any better. Those 'HC04 oscillators are all the same.
I’m aware they’re a generic design but I just wondered if they’re worth using or would be outperformed by a better quality part. If they’re fake/rubbish then I’ll change it but if it’s any good may as well stick with it!
If you are happy with it, why change again.
I doubt that you will be able to hear the difference.
If you are replacing the basic crystal oscillator using a logic ic ( which maybe inbuilt as in a Philips chipset ), then it will be an upgrade.
Beware though of some players that use a better oscillator using a colpitts oscillator ( Arcam )

Ultra low phase noise oscillator
TCXO is Temp Compensated Crystal Oven.
The temp compensation gives very low drift but says nothing about jitter.
The linked oscillators above are low jitter.
