need help identifying a small soic-10 marking code.

Hi

I tried taking a shot of the ic to post here, but my phone cam took crappy images, when I tried to get closer to the pcb to have a clear shot of the ic everything looked like a smudge. Also I tried searching google images for something of the like, but the aspect ratios of the images were not as the ic, so please bare with me.

The ic is very small, it's an smd soic-10 (I suspect), it's about half the width of the soic-8 ic with 10 terminals !!! and rather more elongated parallel to the terminals (as if it were pulled apart by it's terminals like an elastic band)

there are two lines of markings, the first contains the characters "78TI", and the second contains the characters "AIR". The ic is a part of a wireless optical mouse, and i'm not sure if it was only the mouse controller, or controller/transmitter.

I've searched the web far and wide, on google, mouser, digikey, ti.com, st.com and others i don't recall at the moment, and I coulden't find anything near.

Thank you for your help, and any contribution is appreciated.

Hey Cairo_guy,

Mice of low cost, high-volume highly -competitive consumer products with special features only found in ASICs which are proprietary to the owner. Thus, web documents will not be available. That's the way it is.

Thanks for your replies, and I hope these pictures help, they are far from clear though, but I wrote the markings in my first post.
