7.0 Delay-Locked Loop (DLL) Description
XPressArray-II devices employ clock tree synthesis, enabling
an unlimited number of clock and reset signals to be routed.
Synthesized clock trees deliver high speed clock signals with
minimal skew and power.
The XPressArray-II DLL (Figure 6) is an all digital clock
management function embedded into the XPressArray-II
bases. DLLs may be used to minimize clock insertion delay,

perform basic clock frequency synthesis and generate phase
shifts. The DLL provides both coarse and fine-grained phase
shifting with dynamic phase shift control. The quadrature clock
generation features deliver accurate clock phases at the load,
compensating for clock tree delays across the full range of
temperature and voltage. In clock divider and clock doubling
applications, duty cycle correction is available. A robust real-
time lock detection circuit completes the DLL.
