Default Define what clock is this?

Hello, after regroup my electronic components i've found on clock: with this sign:
-----------------
/ <T> 9350T \
| XO - 105BIC |
|.14.31818MHz /

Is this ordinary or some kind "special" clock?
Thank You!

Hi

In the answer, information is given. It indicates the frequency isn't a multiple of 44.1 kHz o no use for audio. And even if the frequency was correct, if it is designed to clock Apple computers, it won't be optimised for low jitter either.

14.318 is 4x the NTSC colourburst frequency of 3.58MHz.

It could be for a TV, a VCR etc. The previously mentioned Apple II was one of many home computers which used related frequencies. Divide by 15 and you have a 0.95MHz clock for the 6502. It would be synchronous with the video circuitry which helps a great deal.

As others have said, it has nothing to do with 44.1kHz audio, though if you divide by 325 you get close...

David.
