PMW3610DM-SUDU provides enhanced features such as programmable resolution, configurable sleep and wake up time to suit various wireless optical navigation applications. the advanced class of vcsel was engineered by pixart to provide a laser diode with a single longitudinal and a single transverse mode. the laser sensor is packaged into a 16-pin integrated molded lead- frame (dip) package. it is designed to be used with lm18-lsi lens to achieve the optimum performance. together these parts provide a complete and compact navigation system without moving parts. laser calibration process is not required; it is pre-calibrated at sensor level which helps to facilitate high volume assembly. theory of operation the sensor is based on pixart laser technology, which measures changes in position by optically acquiring sequential surface images (frames) and mathematically determines the direction and magnitude of movement. it contains an image acquisition system (ias), a digital signal processor (dsp), and a three 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 x and y relative displacement values. an external microcontroller reads the x and y information from the sensor serial port. the microcontroller then translates the data into usb or rf signals before sending them to the host pc or game console. features ? small form factor molded lead frame 16-pin dip package ? single low operating voltage: 1.7 ? 2.1v ? 12-bits motion data registers ? high speed motion detection up to 30ips and acceleration up to 10g ? advanced technology 832-865nm wavelength vcsel (single mode) ? pre-calibrated laser power ? compliance to iec/en 60825-1 eye safety - class 1 laser power output level - on-chip laser fault detection circuitry ? motion detect pin output ? internal oscillator ? no clock input needed ? built-in laser control mosfet ? 3-wire spi communication with nreset ? improved dust robustness ? enhanced programmability - resolution up to 3200 cpi with 200 cpi step - downshift and wake up time - sensor orientation applications ? laser mice ? optical trackballs ? motion input devices
