Figure 3. Block diagram
The PAN301A is a high performance CMOS-process optical mouse sensor with DSP integration chip that
serves as a non-mechanical motion estimation engine for implementing a computer mouse. It is based on
new optical navigation technology, which measures changes in position by optically acquiring sequential
surface images (frames) and mathematically determining the direction and magnitude of movement. The
sensor is in a 20pin optical package. The output format is two-channel quadrature (X and Y direction),
which emulates encoder phototransistors. The current X and Y information are also available in registers
accessed via a serial port.
