4.2.3.1. Clocks

The PHY Lite for Parallel Interfaces Intel® FPGA IP sources a reference clock from a dedicated clock pin to the PLL inside the IP. This PLL provides four clock domains for the output and input paths.

Table 59.   PHY Lite for Parallel Interfaces Intel® FPGA IP Clock Domains
Clock Domain Description
Core clock The IP generates this clock internally and uses it for all transfers between the FPGA core fabric and I/O banks. The clock phase alignment (CPA) circuitry keeps the clock in phase with the PHY clock for transfers between the core and the periphery.
PHY clock The IP uses this clock internally for PHY circuitry running at the same frequency as the core clock.
VCO clock The PLL generates this clock internally. The input and output paths use the VCO clock to generate interpolator delays that compensates for PVT variations.
Interface clock This is the clock frequency of the external device connected to the FPGA I/Os.
