Data rate doubler for electrical backplane

摘要

High data rate I/O modules may be placed on a synchronous bus used also with legacy low data rate I/O modules without rendering the latter modules incompatible and without changing the clock rate of the bus by interleaving extended data to be read at falling edges of the clock with conventional data for the legacy modules to be read at rising edges of the clock. High data rate modules read both extended and conventional data effectively doubling the data transmission rate.
