Source 13.824 MHz Xtal oscillator for 11/23 M8186

[peterbbu]

My KDF11 11/23 CPU M8186 has a broken 13.824 Mhz xtal oscillator (metal cased - fits DIL14) 4 pins used is faulty. I am having difficulty in locating a suitable replacement.

I have found a 12 MHz and a 13 MHz part but not a 13.824 Mhz part.

a) will it run ok, though slightly slower with either of these?

b) does anyone either have such a xtal oscillator or can point me to a supplier


Thanks

Peter

Does AliExpress ship to the UK?

or there's always eBay (also in China)

I have run a KDF11 stable at 18 MHz. But I guess it may vary from board to board. Use anything close , higher or lower. Should’t be a problem.

If you absolutely need to get a custom frequency oscillator, DigiKey (and I assume other vendors) offer these products:

https://www.digikey.com/en/products/filter/programmable-oscillators/169?s=N4IgjCBcoGwJxVAYygMwIYBsDOBTANCAPZQDaIALGGABxwDsIAuoQA4AuUIAyuwE4BLAHYBzEAF9CYOHUQgUkDDgLEyIAAzNxkkACY1RbEgGZM6dkT5agA

these are the DIP versions, SMT versions are also available. Basically they can program a custom frequency for you. I have used this service, works great.
