7.3.5. PHY Clock (PHYCLK) Networks
The PHYCLK network is a dedicated high-speed, low-skew balanced clock tree designed for a high-performance external memory interface.
The top and bottom sides of the Stratix® V devices three PHYCLK networks each. Each PHYCLK network spans across one I/O bank and is driven by one of the left, right, or center PLLs located at that device side.
The following figure shows the PHYCLK networks available in the Stratix® V devices.
The PHYCLK network can be used to drive I/O sub-banks in each I/O bank. Each I/O sub-bank can be driven by only one PHYCLK network—all I/O pins in an I/O sub-bank are driven by the same PHYCLK network. The UniPHY IP for Stratix V devices uses the PHYCLK network to improve external memory interface performance.
