High-Speed Random-Data Generator Facilitates Eye Diagrams

Abstract: A handful of components are integrated into a circuit that creates a high-quality random data stream
that generates eye diagrams up to 62.5MHz. The circuit diagram and eye diagram are shown.

The eye diagram, one of the best figures of merit for evaluating robustness in a digital data link, shows a single
bit window (bit N), preceded by a random-value bit (N-1) and followed by a random-value bit (N+1).

Communications-systems engineers usually have access to the sophisticated test equipment required to measu
