Abstract

Advanced panchromatic, multispectral, and hyperspectral imaging applications from the visible through the longwave IR, are pushing image sensor to higher line and frame rates, wider fields-of-view, and high spatial and spectral resolution. When implemented with realistic focal plane architectures, the resulting multiple parallel output video streams must operate at high pixel data rates and with excellent amplitude resolution. The video signal chains necessary to process and digitally encode the raw pixel video must operate at very high speed, with low noise and wide pixel dynamic range. We discuss issues and constraints associated with advanced video signal chain circuit board design, including methods to improve settling times, electrical crosstalk, and the implementation of grounding approaches needed to ensure low noise. We describe the design and fabrication of a one-channel prototype signal chain board designed to operate at 14-bits and 20 MHz. In addition, we discuss video signal chain testing and verification constraints and report on noise, step response and differential nonlinearity measurements made on our prototype signal chain board.
