These gearboxes have three stage pipeline registers. The first stage registers sample the high-speed input data by
the high-speed edge clock on its rising and falling edges. The second stage registers perform data alignment
based on the control signals UPDATE and SEL0 from the control block. The third stage pipeline registers pass the
data to the device core synchronized to the low-speed system clock. Figure 2-16 shows a block diagram of the
input gearbox.
