I second this, for the life of me, I can't find it. Just data specs and how most of the electronics retailers online says it obsolete, specially since Avago got absorbed by Broadcom.
Any update where to get a new sensor? I just received a device from a friend and it needs to be fixed.
The easier path would be to install a rotary encoder, and call it a day. If you do find the sensor, you have to code basically a driver for it and print your own pattern.
