Notes to Figure 2–27:
(1) IQ lines are inter-transceiver block lines.
(2) There are four receiver PLLs in each transceiver block.
The receiver PLL can also drive the fast regional, regional clocks, and
local routing adjacent to the associated transceiver block. Figures 2–28
through 2–31 show which fast regional and regional clock resource can be
used by the recovered clock.
