... Theory of Operation The ADNS-3000 is based on Optical Navigation Technol- ogy, which measures changes in position by optically acquiring sequential surface images (frames) and math- ematically determining the direction and magnitude of movement. The ADNS-3000 contains an Image Acquisition System (IAS), a Digital Signal Processor (DSP), and a four wire serial port ...

... Avago Technologies provides an IGES file drawing de scribing the base plate molding features for lens and PCB align- ment. The ADNS-3000 sensor is designed for mounting on a through-hole PCB, looking down. There is an aperture stop and features on the package that align to the lens. The ADNS-5110-001 lens provides optics for the imaging of the surface as well as the illumination of the surface at the optimum angle ...

... For improved electrostatic discharge performance, typical creepage and clearance distance are shown in the table below. Assumption: base plate construction is as per the Avago Technologies supplied IGES file and ADNS-5110- 001 lens. Note that the lens material is polycarbonate or polysty rene HH30. Therefore, cyanoacrylate based adhe- ...

... Synchronous Serial Port The synchronous serial port is used to set and read pa- rameters in the ADNS-3000, and to read out the motion information. The port is a four wire serial port. The host micro-con troller always initiates communication; the ADNS-3000 never initiates data transfers. SCLK, MOSI, and NCS may be driven directly by a micro-controller ...

... The first byte contains the address, is sent by the micro-controller over MOSI, and has a “0” as its MSB to indicate data direction. The second byte contains the data and is driven by the ADNS-3000 over MISO. The sensor outputs MISO bits on falling edges of SCLK and samples MOSI bits on every rising edge of SCLK. ...

... A full reset will thus be ex- ecuted and any register settings must be reloaded. Power Down The ADNS-3000 can be set to Power Down mode by writ- ing 0x02 to register 0x0d to disable the sensor. In addi- tion, the SPI port should not be accessed during power down. Other ICs on the same SPI bus can be accessed, as long as the sensor’ ...
