BRIEF HS CLOCK TIMING TEST DESCRIPTIONS
Name
Purpose
TLP-01
To verify that the duration (TLPX) of the final Clock Lane LP-01 state immediately before
HS transmission is greater than the minimum conformant value.
TCLK-PREPARE
To verify that the time that the DUT Clock Lane transmitter drives LP-00 (TCLK-PREPARE)
prior to driving TCLK-ZERO when entering HS mode, is within the conformance limits.
TCLK-ZERO
To verify the time that the DUT Clock Lane transmitter drives the extended HS-0
differential state prior to starting clock transmission
TCLK-PREPARE+ZERO
To verify that the combined time of TCLK-PREPARE plus the time that the DUT Clock Lane
transmitter drives the extended HS-0 differential state prior to starting clock
transmission (TCLK-ZERO) is greater than the minimum required duration.
TCLK-TRAIL
To verify that the duration that the DUT Clock Lane HS transmitter drives the final HS-0
differential state following the last payload clock bit of a HS transmission burst (TCLK-
TRAIL) is greater than the minimum required value.
TREOT
To verify that the 30%-85% Post-EoT Rise Time (TREOT) of the DUT LP Clock Lane
transmitter is within the conformance limits.
TEOT
To verify that the interval measured from the start of the DUT Clock Lane HS
transmitter’s TCLK-TRAIL to the start of the first Clock Lane LP-11 state (TEOT) is less
than the maximum allowed limit.
THS-EXIT
To verify that the duration that the Clock Lane transmitter remains in the LP-11 (Stop)
state after exiting HS mode (THS-EXIT), is greater than the minimum required value.
UIinst
To verify that the Instantaneous Unit Interval values (UIINST) of the DUT HS Clock are
within the conformance limits.
HS-Bitrate
To verify the Bitrate of the DUT HS Clock is within conformance limits.
BRIEF HS COMMON MODE TEST DESCRIPTIONS
Name
Purpose
VCMTX-DATA-1
To verify that the Static Common-Mode Voltages (VCMTX(1), and VCMTX(0)) of the
DUT Data & Clock Lanes HS transmitter are within the conformance limits.
VCMTX-DATA-0
VCMTX-CLK-1
VCMTX-CLK-0
dVCMTXLF-DATA
To verify that the AC Common-Mode Signal Level Variations between 50 and 450MHz
(ΔVCMTX(LF)) of the DUT Data & Clock Lanes HS transmitter are less than the
maximum allowable limit.
dVCMTXLF-CLK
dVCMTXHF-DATA
To verify that the AC Common-Mode Signal Level Variations above 450MHz
(ΔVCMTX(HF)) of the DUT Data & Clock Lanes HS transmitter are less than the
maximum allowable limit.
dVCMTXHF-CLK
