1 / 32 page  ADNS-7550 Integrated molded lead-frame DIP Sensor Data Sheet Theory of Operation The ADNS-7550 integrated molded lead-frame DIP sensor comprises of sensor and VCSEL in a single package. The advanced class of VCSEL was engineered by Avago Technologies to provide a laser diode with a single lon- gitudinal and a single transverse mode. In contrast to most oxide-based single-mode VCSEL, this class of Avago VCSEL remains within single mode operation over a wide range of output power. It has significantly lower power consumption than a LED. It is an excellent choice for optical navigation applications. The sensor is based on LaserStream™ technology, which measures changes in position by optically acquiring se- quential surface images (frames) and mathematically determining the direction and magnitude of movement. It 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 il- lumination system. These images are processed by the DSP to determine the direction and distance of motion. The DSP calculates the Δx and Δy relative displacement values. An external microcontroller reads the Δx and Δy information from the sensor serial port. The microcon- troller then translates the data into PS2, USB, or RF signals before sending them to the host PC or game console.
