Abstract :
This paper proposes an approach to data transfer that can potentially achieve high rates without requiring the ultra fast clocks of other approaches, or extra wide buses. The idea is to transfer multiple bits over each pin within each clock cycle using modulation techniques common in communication systems. Phase modulation is simple in implementation and demonstrates 160 Mb/s peak transfer rate per pin using a 20 MHz clock. This scheme may prove effective for chip-to-chip or system bus interface both on printed circuit boards (PCBs) and multi-chip modules (MCMs).<>
