So I cracked open my AVRISP mkII and noticed that there is an incredibly small crystal on the ATMega128 inside that is approximately 3mm x 1.0mm (long and skinny) with no additional load capacitance. It looks like the letters "AJ" are written on it, but otherwise there are no distinguishing markings.
Does anybody happen to know what this crystal model / manufacturer is? I would love to start using it in designs. :D Thanks!
