1.6. Test Result Comments
In each test case, the RX JESD204B IP core successfully initialize from CGS phase, ILA phase, and until user data phase. No data integrity issue is observed by the PRBS checker.
In deterministic measurement test case DL.3, the link clock count in the FPGA depends on the board layout and the LMFC offset value set in the ADC register. The link clock count can vary by only one link clock when the FPGA and ADC are reset or power cycled. The link clock variation in the deterministic latency measurement is caused by word alignment, where the control characters fall into the next cycle of data some time after realignment. This makes the duration of ILAS phase longer by one link clock some time after reset or power cycle.
