High-speed designs using single-ended ECL signals need careful design to avoid noise and crosstalk prob-
lems. The following suggestions can aid obtaining a reliable system:
1. Wide noise margins on input signals.
2. Avoid SSOs. Simultaneous switching outputs will degrade timing margins by increasing AC delay val-
ues, and reducing noisethresholds.
3. Provide good signal terminations and well-matched board traces in addition to well-controlled power
supplies.
