Abstract
A high-speed network switch includes a data bus for transmitting data between devices. The data bus includes a plurality of data lines and a clock line. As packet data is received by the high-speed network switch, the packet data is divided into byte-wide cells for transmission over the data lines. While the cells are transmitted over the data lines, a half-speed clock is transmitted over the clock line. Transitions in the half-speed clock occur during transmission of the cell data. The transitions are used by a receiving device to sample the byte-wide cells.
