DCM Timing Parameters
All devices are 100% functionally tested. Because of the dif-
ficulty in directly measuring many internal timing parame-
ters, those parameters are derived from benchmark timing
patterns. The following guidelines reflect worst-case values
Operating Frequency Ranges
across the recommended operating conditions. All output
jitter and phase specifications are determined through sta-
tistical measurement at the package pins.

Notes:
1. “DLL outputs” is used here to describe the outputs: CLK0, CLK90, CLK180, CLK270, CLK2X, CLK2X180, and CLKDV.
2. If both DLL and CLKFX outputs are used, follow the more restrictive specification.
3. If the CLKIN_DIVIDE_BY_2 attribute of the DCM is used, then double these values.
