Working circuit for a xtal oscillator cmos inv at 10 MHz

Has anybody ever managed to implement an oscillator with 10 MHz crystal and a CMOS inverter? One that really worked.

Could I see that circuit?

It seems that I cannot go further than 4MHz using the 74HC04.

Theory I read a lot but did not found a circuit said to actually work.

Try a 74S04 or 74F04

TTL is faster than CMOS in some cases, though power use is quite high.

Or, use an oscillator with the crystal, inverter, etc. integrated in the 4 pin "can"
