2.9. Phase Detector for VT Tracking
There may be variations in the read and write paths caused by voltage and temperature changes. The phase detector keeps track of the variation of the mimic clock to optimize the system timing.
Figure 8. VT Tracking System Overview
In the Intel® MAX® 10 external memory interface solution, the memory clocks are used to mimic the read and write paths. The memory clock pins loop back to the phase detector as a mimic clock. The phase detector provides any variation of the mimic clock to the sequencer. The sequencer adjusts the read capture clock to match the clock phase change.
