agilent ADNS-2030 optical mouse sensor product overview description high performance, low power optical mouse sensor suitable for cordless precision optical navigation the ADNS-2030 is a low power reflective optical sensor that provides a non-mechanical tracking engine for implementing a computer-pointing device. it is based on optical naviga- tion technology which measures changes in position by optically acquiring sequential surface images up to 2300 times per second and math- ematically determining the direction and magnitude of movement at the maximum of 800 counts per inch (cpi) and at speeds up to 14 inches per second (ips). agilent provides the complete optical mouse sample kit (part # adnk-2030). the cmos based sensor is mounted in a 16-pin stag- gered dual inline package (dip) and designed for use with the hdns-2200 (led assembly clip) and hlmp-ed80- xxxxx (639 nm led illumination source) and hdns-2100 (lens). with its low power feature, this optical mouse sensor enables longer battery life and more efficient power consump- tion. this eliminates the need for a recharger and making it an ideal choice for cordless optical mouse application. theory of operation the ADNS-2030 is based on optical navigation technology. it contains an image acquisition system (ias), a digital signal processor (dsp), a two-channel quadrature output, and a two-wire serial port. the ias acquires microscopic surface images via the lens and illumination system provided by the hdns-2100, 2200, and hlmp-ed80-xxxxx. these images are processed by the dsp to determine the direction and distance of motion. the dsp generates the (delta)x and (delta)y relative displace- ment values that are converted into two channel quadrature signals. other optical mouse sensors available from agilent technologies adns-2610 adns-2620 hdns-2000 adns-2051 features precise optical navigation technology no mechanical moving parts complete 2d motion sensor serial interface and/or quadrature interface smooth surface navigation programmable frame speed up to 2300 frames per sec (fps) accurate motion up to 14 ips 800 cpi resolution high reliability high speed motion detector wave solderable single 3.3 volt power supply shutdown pin for usb suspend mode operation power conservation mode during times of no movement on chip led drive with regulated current serial port registers ? programming ? data transfer 16-pin staggered dual inline package (dip) applications cordless optical mice mice for desktop pcs, workstations, and portable pcs trackballs integrated input devices figure 1. the navigation engine identifies common features in sequential images to determine the direction and amount of mouse movement. image b was taken while the mouse was moving, a short time after image a. figure 2. exploded view drawing of optical mouse components. hdns-2200 (clip) hlmp-ed80-xxxxx (led) ADNS-2030 (sensor) customer supplied pcb hdns-2100 (lens) customer supplied base plate with recommended alignment features per iges drawing a b navigation by two images comparison
