Anyone know what this frequency is for? I have a crystal in my bin of pulls, no idea what
I pulled it from (my guess would be an old dead ISA modem or sound card, given where most
of my pulls came from). It doesn't divide nicely into NTSC or PAL color subcarriers
(my normal assumption for weird frequencies), but it it's still a pretty common part.
The one place I found it mentioned that wasn't a datasheet site had something (maybe)
to do with DTMF decoding:

Any ideas?
