Precision Illumination Signal Modulation (PrISM)

Overview

General Description

Symbol Diagram

The Precision Illumination Signal Modulation (PrISM) component uses a linear feedback shift register (LFSR) to generate a pseudo random sequence. The sequence outputs a pseudo random bit stream, as well as up to two user-adjustable pseudo random pulse densities. The pulse densities may range from 0 to 100 percent.

Features

  • Programmable flicker-free dimming resolution from 2 to 32 bit
  • Two pulse density outputs
  • Programmable output signal density
  • Serial output bit stream
  • Continuous run mode
  • User-configurable sequence start value
  • Standard or custom polynomials provided for all sequence lengths
  • Kill input disables pulse density outputs and forces them low
  • Enable input provides synchronized operation with other components
  • Reset input allows restart at sequence start value for synchronization with other components
  • Terminal Count Output for 8-, 16-, 24-, and 32-bit sequence lengths.
