Abstract :
We have analyzed the power distribution system and signal integrity of a silicon-on-silicon multichip module designed for for asynchronous transfer mode (ATM) switching applications. The module contains four AT&T T7650 Phoenix 8-bit parallel buffered 2×2 switching node ICs configured into a 4×4 node with an operating frequency of 40 MHz. We compared the signal integrity of the design based on our MCM technology with that of typical PWB technologies. The results indicate that crosstalk and ringing are greatly reduced in MCM-based designs. We also investigated the effectiveness of decoupling capacitors on simultaneous switching noise, comparing the performance of ring- and plane-type power distribution systems. For this example, we find little difference between the two for signal rise times greater than 2 ns
