Hi!

I has an old IR remote control which has a LM3714AM from sharp. No
more on the board than the chip, a couple of caps and a small blue box
(a xtal?). You can have a look at

   ftp://ftp.iac.es/out/dsg/LR3714AM/chip.png
   ftp://ftp.iac.es/out/dsg/LR3714AM/xtal.png

(the chip is on one side of the PCB and the caps and blue box on the
opposite)

The thing is that the two pins blue box has one of them broken. I have
unsuccesfully search the datasheet of the LR3714AM. I think the box is
the xtal, but at which freq.?

Any tips?

Thanks,
Diego.
