Additional Details

The SAS1068X processes the quadrature signals from an incremental encoder to generate digital outputs indicating the position and direction of movement. The multiplication modes (x1, x2, x4) enhance the resolution of the encoder, providing finer position control. The built-in digital noise filter minimizes the effects of electrical noise and signal jitter, ensuring accurate and reliable counting.

The index pulse input allows for resetting the counter to a known reference point. LSI Computer Systems provides a datasheet containing detailed information on the SAS1068X, including pin configurations, electrical characteristics, and timing diagrams. Proper implementation and understanding of the datasheet are essential for successful integration into a system. It is often used in a PLCC or similar surface mount package.
