188.8.131.52. Clock Tree
The Intel® Arria® 10 external memory interface PHY clock network is designed to support the 1.2 GHz DDR4 memory standard.
Compared to previous generation devices, the PHY clock network has a shorter clock tree that generates less jitter and less duty cycle distortion.
The PHY clock network consists of these clock trees:
- Reference clock tree
- PHY clock tree
- DQS clock tree
