Purpose
TLP-01
To verify that the duration (TLPX) of the final Data Lane LP-01 state immediately
before HS transmission is greater than the minimum conformant value.
THS-PREPARE
To verify that the duration of the final LP-00 state immediately before HS
transmission (THS-PREPARE) is within the conformance limits.
THS-ZERO
To verify the time the DUT Data Lane transmitter drives the HS-0 differential state
prior to transmitting the HS Sync sequence.
THS-PREPARE+ZERO
To verify that the combined time of THS-PREPARE plus the time the DUT Data Lane
transmitter drives the HS-0 differential state prior to transmitting the HS Sync
sequence (THS-ZERO) is greater than the minimum required duration.
THS-SYNC
To verify the time to transmit of the HS Sync sequence before the first bit of data is
transmitted.
THS-TRAIL
To verify that the duration the DUT Data Lane TX drives the inverted final differential
state following the last payload data bit of a HS-TX burst (THS-TRAIL), is greater than
the minimum required value.
TEOT
To verify that the combined duration of the THS-TRAIL plus TREOT intervals (a.k.a.
TEOT) of the DUT Data Lane transmitter is less than the maximum allowed value.
TREOT
To verify that the 30%-85% Post-EoT Rise Time (TREOT) of the DUT LP Data Lane
transmitter is within the conformance limits.
THS-EXIT
To verify that the duration that the Data Lane transmitter remains in the LP-11 (Stop)
state after exiting HS mode (THS-EXIT), is greater than the minimum required value.
