“It is already Thanksgiving and I am still posting chips from the iPhone. This is a mystery chip from the iPhone with limited information on the package and “PMA19″ on the die. After taking a close look at the surface at 400x total magnification, I still couldn’t see any hint of the origin of the chip. The only guess that I could make is that it it might be an RF modulator/demodulator with a built in DSP. If anyone has some insight, feel free to post a comment.”
