At a meeting today, an age-old engineer was ranting about an old bus technology we have deployed. He said that because it uses Low Power Schottky logic for drivers at each node, that makes the bus niosey, and the more nodes, the more noise. He said the noise is generated because of the Schottky logic. I think this is wrong. I think he's confused with the lower noise margin due to the switching levels ( only .3V margin for sensing a 'low' and .7V margin for sensing a 'high ) The noise issue is because of the narrow noise margins, and not that Schottky logic genertes more noise. Any thoughts?
