Agilent ADNB-6031 and ADNB-6032 Low Power Laser Mouse Bundles
Datasheet
Description The Agilent ADNB-6031 and ADNB-6032 low power laser mouse bundles are the world’s first laser-illuminated system enabled for cordless application. Powered by Agilent LaserStream technology, the mouse can operate on many surfaces that proved difficult for traditional LED-based optical navigation. Its high-performance, low power architecture is capable of sensing high-speed mouse motion while prolonging battery life, two performance areas essential in demanding cordless applications. The ADNS-6030 sensor along with the ADNS-6120 or ADNS6130-001 lens, ADNS-6230-001 clip and ADNV-6330 VCSEL form a complete and compact laser mouse tracking system. There are no moving part, which means high reliability and less maintenance for the end user. In addition, precision optical alignment is not required, facilitating high volume assembly. This document will begin with some general information and usage guidelines on the bundle set, followed by individual detailed information on ADNS6030 laser mouse sensor, ADNV-6330 VCSEL, ADNS6120 or ADNS-6130-001 lens and ADNS-6230-001 clip.

Shown with ADNS-6130-001 Laser Mouse Lens, ADNS6230-001 VCSEL Assembly Clip and ADNV-6330 VCSEL. The components interlock as they are mounted onto defined features on the base plate. The ADNS-6030 laser mouse 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 ADNV-6330 VCSEL is recommended for illumination provides a laser diode with a single longitudinal and a single transverse mode. It is particularly suited as lower power consumption and highly coherent replacement of LEDs. It also provides wider operation range while still remaining within single-mode, reliable operating conditions.
The ADNS-6120 or ADNS6130-001 Laser Mouse Lens is designed for use with ADNS6030 sensor and the illumination subsystem provided by the assembly clip and the VCSEL. Together with the VCSEL, the lens provides the directed illumination and optical imaging necessary for proper operation of the Laser Mouse Sensor. ADNS-6120 and ADNS-6130-001 are precision molded optical components and should be handled with care to avoid scratching of the optical surfaces. ADNS-6120 also has a large round flange to provide a long creepage path for any ESD events that occur at the opening of the base plate.
The ADNS-6230-001 VCSEL Assembly Clip is designed to provide mechanical coupling of the ADNV-6330 VCSEL to the ADNS-6120 or ADNS-6130-001 lens. This coupling is essential to achieve the proper illumination alignment required for the sensor to operate on a wide variety of surfaces. Agilent Technologies provides an IGES file drawing describing the base plate molding features for lens and PCB alignment.

Assembly Recommendation 1. Insert the sensor and all other electrical components into the application PCB (main PCB board and VCSEL PCB board). 2. Wave-solder the entire assembly in a no-wash solder process utilizing a 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 4
aperture from direct solder contact. 3. Place the lens onto the base plate. 4. Remove the protective kapton tape from the optical aperture of the sensor. Care must be taken to keep contaminants from entering the aperture. 5. Insert the PCB assembly over the lens onto the base plate. The sensor aperture ring should self-align to the lens. 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.
6. Remove the protective cap from the VCSEL. 7. Insert the VCSEL assembly into the lens. 8. Slide the clip in place until it latches. This locks the VCSEL and lens together. 9. Tune the laser output power from the VCSEL to meet the Eye Safe Class I Standard as detailed in the LASER Power Adjustment Procedure. 10. Install the mouse top case. There must be a feature in the top case (or other area) to press down onto the sensor to ensure the sensor and lens are interlocked to the correct vertical height.

LASER Drive Mode The laser is driven in pulsed mode during normal operation. A calibration mode is provided which drives the laser in continuous (CW) operation. Eye Safety The ADNS-6030 and the associated components in the schematic of Figure 5 are intended to comply with Class 1 Eye Safety Requirements of IEC 60825-1. Agilent Technologies suggests that manufacturers perform testing to verify eye safety on each mouse. It is also recommended to review possible single fault mechanisms beyond those described below in the section “Single Fault Detection”. Under normal conditions, the ADNS6030 generates the drive current for the laser diode (ADNV-6330). In order to stay below the Class 1 power requirements, LASER_CTRL0 (register 0x1a), LASER_CTRL1 (register 0x1f), LSRPWR_CFG0 (register 0x1c) and LSRPWR_CFG1 (register 0x1d) must be programmed to appropriate values. The system comprised of the ADNS-6030 and ADNV-6330, is designed to maintain the output beam power within Class 1 requirements over components manufacturing tolerances and the recommended temperature range when adjusted per the procedure below and implemented as shown in the recommended application circuit of Figure 5. For more information, please refer to Agilent ADNB-6031 and ADNB-6032 Laser Mouse Sensor Eye Safety Application Note AN 5230.
LASER Power Adjustment Procedure 1. The ambient temperature should be 25C +/- 5C. 2. Set VDD to its permanent value. 3. Set the Range bit (bit 7 of register 0x1a) to 0. 4. Set the Range_C complement bit (bit 7 of register 0x1f) to 1. 5. Set the Match_bit (bit 5 of register 0x1a) to the correct value for the bin designation of the laser being used. 6. Set the Match_C_bit (bit 5 of register 0x1f) to
