5.2.2. Clocks
The PHY Lite for Parallel Interfaces Intel® FPGA IP for Stratix® 10 devices uses a reference clock that is sourced from a dedicated clock pin to the PLL inside the IP. This PLL provides four clock domains for the output and input paths.
Clock Domain | Description |
---|---|
Core clock | This clock is generated internally by the IP and it is used for all transfers between the FPGA core fabric and I/O banks. The clock phase alignment circuitry ensures that this clock is kept in phase with the PHY clock for core-to-periphery and periphery-to-core transfers. |
PHY clock | This clock is used internally by the IP for PHY circuitry running at the same frequency as the core clock. |
VCO clock | This clock is generated internally by the PLL. It is used by both the input and output paths to generate PVT compensated delays in the interpolator. |
Interface clock | This is the clock frequency of the external device connected to the FPGA I/Os. |
Core Clock Rate | Speed Grade –1 (MHz) | Speed Grade –2 (MHz) | Speed Grade –3 (MHz) | |||
