ADNS-3000 Low Power Optical Mouse Sensor Data Sheet Description Features The Avago Technologies ADNS-3000 is a low power, small form factor optical mouse sensor. It has a new low-power architecture and automatic power management modes, making it ideal for battery, power-sensitive applications – such as cordless input devices.  Low Power Architecture The ADNS-3000 is capable of high-speed motion detection – up to 30 ips and 20 g. In addition, it has an on-chip oscillator and requires an external resistor to set the LED current.  High Speed Motion Detection up to 30 ips and 20 g The ADNS-3000 along with the ADNS-5110-001 lens, and HSDL-4261 IR LED or HLMP-EG3E-xxxxx Red LED form a complete and compact mouse tracking system. There are no moving parts and this translates to high reliability and less maintenance for the end user. In addition, precision optical alignment is not required, facilitating high volume assembly.  Selectable Resolution of up to 2000 cpi The sensor is programmed via registers through a fourwire serial port. It is housed in an 8-pin staggered dual in-line package (DIP).  Small Form Factor  Programmable Periods / Response Times and Downshift Times from one mode to another for the Power-saving Modes  External Interrupt Output for Motion Detection  Internal Oscillator – no clock input needed  Operating Voltage: as low as 1.7 V  Four-wire Serial Port Interface Applications  Optical mice and optical trackballs  Integrated input devices  Battery-powered input devices Theory of Operation The ADNS-3000 is based on Optical Navigation Technology, which measures changes in position by optically acquiring sequential surface images (frames) and mathematically 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. The IAS acquires microscopic surface images via the lens and illumination system. These images are processed by the DSP to determine the direction and distance of motion. The DSP calculates the Dx and Dy relative displacement values An external microcontroller reads and translates the Dx and Dy information from the sensor serial port into PS2, USB, or RF signals before sending them to the host PC.

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. Features on the lens align it to the sensor, base plate, and clip with the LED. The LED clip holds the LED in relation to the lens. The LED must be inserted into the clip and the LED’s leads formed prior to loading on the PCB. The LEDs recommended for illumination include HSDL-4261 IR LED, HLMP-EG3E-xxxxx Red LED. 26 1.024 25.00 2X 0.984 2.00 3X 0.079 0.383999 0.015118 1.00 0.039 12.9 0.508 12.60 0.496 11.22 0.442 Optional hole for alignment post if used 3.00 ø 0.118 Notes: Clear zone 1.

Figure 6. Exploded View of Assembly PCB Assembly Considerations 4. This sensor package is only qualified for wave-solder process. 5. Wave solder the entire assembly in a no-wash solder process utilizing solder fixture. The solder fixture is needed to protect the sensor during the solder process. It also sets the correct sensor-to-PCB distance as the lead shoulders do not normally rest on the PCB surface. The fixture should be designed to expose the sensor leads to solder while shielding the optical aperture from direct solder contact. 6. Place the lens onto the base plate. 7. Remove the protective Kapton tape from optical aperture of the sensor. Care must be taken to keep contaminants from entering the aperture. Recommend not to place the PCB facing up during the entire mouse assembly process. Recommend to hold the PCB first vertically for the Kapton removal process. 8. Insert PCB assembly over the lens onto the base plate aligning post to retain PCB assembly. The sensor aperture ring should self-align to the lens. 6 10. Install mouse top case. There MUST be a feature in the top case to press down onto the PCB assembly to ensure all components are interlocked to the correct vertical height.

The optical position reference for the PCB is set by the base plate and lens. Note that the PCB motion due to button presses must be minimized to maintain optical alignment. LED DRIVE 1.
