Polling.LFPS Duration Test
Test Summary
This test verifies that the PUT’s Polling.LFPS detector supports the entire tBurst and tRepeat
duration ranges. Durations to be tested:
tBurst = 0.6 us and tRepeat = 6 us
tBurst = 0.6 us and tRepeat = 14 us
tBurst = 1.4 us and tRepeat = 6 us
tBurst = 1.4 us and tRepeat = 14 us
Test Steps and Expected Results
1.
Examiner and the PUT go through the initial steps of the LTSSM (SS.Disabled, Rx.Detect)
to reach Polling.LFPS.
2.
Examiner will generate a Polling.LFPS signal having the first durations specified in the list
above.
3.
Repeat the steps with the following durations listed above.
The test passes if the PUT moves successfully to Polling.RxEQ as per Section
7.5.4.3.2 of the USB 3.0 specification (Exit from Pollling.LFPS).
