PLN2020 twin-eye laser sensor complete navigation sensor that works on virtually all surfaces phili p s laser sensors introduction the philips? PLN2020 twin-eye laser sensor is a high- precision, ultra-fast, low-power consuming, small-sized, single-component, laser-based tracking device for use in computer mice, identification devices, printers and mobile phones. general information the PLN2020 is a fully integrated single-component, robust, self-aligning and small-sized (<180 mm 3 ) laser- based tracking device. the 11-pin 3.85-mm high twin-eye laser sensor has a printed circuit board footprint of a mere 6.8 mm x 6.8 mm and incorporates lenses for its two lasers in the package assembly. thanks to a dedicated lase r power control scheme, energy use is limited to a minimum while power management is maximized, making the device particularly useful for cordless mice. the PLN2020 is based on laser tracking technology. i t measures changes in position by sensing the scattered laser light that is reflected by the surface, and mathematically by on-chip logic and software, determining the direction and magnitude of the movement. it is capable of measuring extremely accurately at a wide range o f speeds. key features design-in simplicity complete single integrated component solution (system-in-package) 11-pin miniature square package intelligent, built-in, multi-mode power managemen t system low-power operation and sleep modes accurate optical navigation smooth and rough surface navigation 3d motion sensor a ccurate motion up to 500 mm/s (20 ips) with an extended motion range up to 1000 mm/s micrometer resolution (800 cpi) single 3.3 volt power supply spi serial bus host interface high-speed serial port registers for programming and data transfer embedded firmware can be upgraded and customized a ctive redundant protection system to ensure lase r safety lead-free wave solderable (or by manual soldering) no mechanical moving parts insensitive to wear and tear the PLN2020 does not require a smooth surface, but can be used on virtually all light-s cattering surfaces, even those with a relatively rough structure. compact in dimensions, the PLN2020 is a true ?system-in-a-package? that is suitable for many applications. as there are no moving parts, and because of its self-aligning optical path, the application of the technology is simple and can be mass- produced in a cost-effective manner without applying expensive aligning procedures.
