Output Gearbox
Each PIC on the top edge has a built-in 8:1 output gearbox. Each of these output gearboxes may be programmed
as a 7:1 serializer or as one ODDRX4 (8:1) gearbox or as two ODDRX2 (4:1) gearboxes. Table 2-10 shows the
gearbox signals.
Table 2-10. Output Gearbox Signal List
The gearboxes have three stage pipeline registers. The first stage registers sample the low-speed input data on the
low-speed system clock. The second stage registers transfer data from the low-speed clock registers to the high-
speed clock registers. The third stage pipeline registers controlled by high-speed edge clock shift and mux the
high-speed data out to the sysIO buffer. Figure 2-17 shows the output gearbox block diagram.
