Physical Interface (e.g. buttons, scrollwheels) OEM

Does anyone know the name of the OEM who produced the ipod click wheel with buttons under the wheel. I think they provide Blackberry with their buttons as well.

For the life of me I can’t remember their name and I can’t find them through googling.

I know i’ve viewed their website in the past.

Can anyone help?

Search for ipod+wheel, the very first result shows the company’s name is Synaptics, gives a cool history about its development, and even shows the internal components:
