Spartan-3 FPGA Family: DC and Switching Characteristics
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
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
through
DLL tables. DLL specifications that do not change with the
Delay-Locked Loop (DLL)

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 F
The CLKIN_DIVIDE_BY_2 attribute can be used to increase the effective input frequency range up to F
CLKIN_DIVIDE_BY_2 divides the incoming clock frequency by two as it enters the DCM.
Industrial temperature range devices have additional requirements for continuous clocking, as specified in
CLKIN input jitter beyond these limits may cause the DCM to lose lock. See

Period jitter and cycle-cycle jitter are two (of many) different
ways of characterizing clock jitter. Both specifications
describe statistical variation from a mean value.
Period jitter is the worst-case deviation from the average
clock period of all clock cycles in the collection of clock peri-
ods sampled (usually from 100,000 to more than a million
samples for specification purposes). In a histogram 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.
