Output DDR Flip Flop allows designers to avoid additional timing complexities and CLB usage.
This design element is a dedicated output register for use in transmitting double data rate (DDR) signals from FPGA devices. This primitive is typically used to drive a clock signal out of the FPGA. This feature allows designers to avoid additional timing complexities and CLB usage. The ODDR also works with SelectIO™ features. For more details refer to SelectIO™ Wizard documentation.
Certain AMD technologies may require third-party enablement or activation. Supported features may vary by operating system. Please confirm with system manufacturer for specific features. No technology or product can be completely secure.
