Abstract
A distributed transmission line network for connecting a plurality of DUTs to a low-power driver includes a plurality of distributed transmission lines with distributed capacitors. The distributed capacitors are added to the distributed transmission lines to make the propagation delay on each line equal, thereby eliminating skewed input signals to the DUTs. The capacitors also minimize capacitive cross-talk between the plurality of distributed transmission lines. The distributed transmission line network includes a driver with an internal resistance that is much less than the characteristic impedance of the distributed transmission line to minimize the voltage drop at the driver. The distributed transmission line also includes an input RC network for speeding rise time and a termination RC network for minimizing reflections in the distributed transmission line.
