Digital Clock Manager (DCM) Timing
For specification purposes, the DCM consists of three key
components: the Delay-Locked Loop (DLL), the Digital Fre-
quency Synthesizer (DFS), and the Phase Shifter (PS).
Aspects of DLL operation play a role in all DCM applica-
tions. All such applications inevitably use the CLKIN and the
CLKFB inputs connected to either the CLK0 or the CLK2X
feedback, respectively. Thus, specifications in the DLL
tables
that only employs the DLL component. When the DFS
and/or the PS components are used together with the DLL,
then the specifications listed in the DFS and PS tables
(Table 106
ing ones in the DLL tables. DLL specifications that do not
change with the addition of DFS or PS functions are pre-
sented in
Period jitter and cycle-cycle jitter are two of many different
ways of specifying clock jitter. Both specifications describe
statistical variation from a mean value.

CLKIN
DLL specifications apply when any of the DLL outputs (CLK0, CLK90, CLK180, CLK270, CLK2X, CLK2X180, or CLKDV) are in use.
The DFS, when operating independently of the DLL, supports lower FCLKIN frequencies. See
To support double the maximum effective FCLKIN limit, set the CLKIN_DIVIDE_BY_2 attribute to TRUE. This attribute divides the incoming
clock frequency by two as it enters the DCM. The CLK2X output reproduces the clock frequency provided on the CLKIN input.
CLKIN input jitter beyond these limits might cause the DCM to lose lock.

Period jitter is the worst-case deviation from the ideal clock
period over a collection of millions of samples. In a histo-
gram of period jitter, the mean value is the clock period.
Cycle-cycle jitter is the worst-case difference in clock period
between adjacent clock cycles in the collection of clock peri-
ods sampled. In a histogram of cycle-cycle jitter, the mean
value is zero.
Spread Spectrum
DCMs accept typical spread spectrum clocks as long as
they meet the input requirements. The DLL will track the fre-
quency changes created by the spread spectrum clock to
drive the global clocks to the FPGA logic. See XAPP469,
Spread-Spectrum Clocking Reception for Displays
for details.
