Avago ADNS-3050 entry level optical gaming sensor.

Small Form Factor Package - 8-pin DIP
Operating Voltage: 2.8V - 3.0V
High Speed Motion Detection up to 160ips on white paper and acceleration up to 23g
High Speed Motion Detection at typical of 60ips and acceleration up to 20g
Selectable Resolution up to 2000cpi
Four wire Serial Port Interface
External Interrupt Output for Motion Detection
Internal Oscillator - no clock input needed
On-chip LED driver
Minimal number of passive components
Programmable power-saving modes for selectable wired or wireless application
Customized responce time and down shift time for rest modes
Configurable LED operating modes and drive current

The specs sound simular to a laser mouse set up, but I find it interesting that they're actually claiming up to 160 IPS of movement. IE 4.0m/s~

With the small form factor and potentially low price, I think this could be a great sensor with enough effort put forth.

We are currently working with this sensor. Look for a mouse or two in Sept.

I couldn't help but notice the 8 bit path in the data sheet. :[ Might be a bottleneck on low Hz settings.

Most sensor have 8 bit data paths but because of the higher "polling rate" that's not a problem.

Just realized that like a min ago lol

ADNS-3060 max speed is over 4.5 m/s, so 4.0 is possible. ADNS-3050 has better CPI though. Pity there's no information concerning LOD or prediction, we have to wait.

Set the resolution of sensor
000: 1000 dpi (default)
001: 250 dpi
010: 500 dpi
011: 1250 dpi
100: 1500 dpi
101: 1750 dpi
110: 2000 dpi
Nice!

Is the 3060 a better sensor?

I could make the Ikari optical easily malfunction well below those speeds. I'd say it's closer to 2m/s on cloth and around 1.5>m/s on wood/hardsurface unless steelseries did something to royalty screw up the mouse. The A4tech Mouse sujoy reviewed back in 07 also malfunctioned at 2.23m/s http://www.esreality.com/?a=longpost&id=1265679&page=20 Of course, that's with actual hardware testing.

Bout Lift off, it seems to be "controllable" through firmware according to the data sheet.

Lift Detection Cutoff Algorithm
When the mouse is raised from the tracking surface which
is also known as lifted condition, there is a specifi c z-height
whereby the tracking of the sensor will cease. However
the tracking cutoff height of the ADNS-3050 sensor varies
with the diff erent tracking surfaces. In general to have a
lower tracking cutoff height than the default settings, the
algorithm illustrated in the form of a pseudo code is recommended
as Z-height monitoring routine in the microcontroller
firmware.
