Mobile Phone Trackpad Datasheet, Pinout

Hi,
I am working on a product design. I need to interface a Mobile Trackpad such as used in Blackberry phones (8520/9300/9700/9800/9900) to a micorcontroller. I am having extreme difficulty in finding pinouts and datasheet for these track pads. There are so many sellers on alibaba, aliexpress and lots of other chinese websites, but all of them I talked with, only tell that their trackpad is compatible with "that" phone, and none of them could produce pinout and datasheet for the part they sell. I could not locate any manufacturer, that manufactures these small track pads and can provide datasheet as well. Digikey, mouser, adafruit, spakrfun none of them has small mobile track pads.

Can someone help me :
1. Find pinouts and Datasheet for these track pads
2. Any good source which sells mobile phone track pads in large quantity and also provides datasheet for the part.

Here is a link to one such track pad i am looking for:

Hello

I am just enquiring if your had found your datasheet for the blackberry track pad, very easy to purchase, but difficult to get a datasheet.
