Latest Patents

Bausman holds a patent for an "Optical Clock Distribution System." This system minimizes clock skew in the distribution of clock signals to individual circuit board components in a highly synchronous, high-speed computer system. The clock system includes both an optical subsystem and an electrical subsystem. The optical subsystem utilizes multiple lasers and an n.times.n passive star coupler to introduce clock redundancy into the system. The lengths of the optical distribution fibers are controlled to ensure they have equivalent optical path lengths. Once delivered to the logic assemblies, the optical clock signals are converted into equivalent electrical clock signals. The electrical subsystem then distributes these converted electrical clock signals to individual circuit board components over equalized fanout paths, minimizing the skew experienced by the components. Additionally, the system compensates for skew introduced by the receiver and fanout electronics by tuning the length of the fiber. The electrical subsystem further includes means for customizing the fanout to fit individual circuit boards, thereby reducing extraneous system noise. The overall clock system achieves a maximum clock distribution network skew of approximately ±100 picoseconds, effectively reducing or eliminating the need for electrical deskew at individual circuit board components.
