BRIEF HS COMMON MODE TEST DESCRIPTIONS

With HS Common Mode selected in the Category field, the following Measure values are available:
VCMTX-DATA-1, VCMTX-DATA-0, VCMTX-CLK-1, VCMTX-CLK-0, dVCMTXLF-DATA, dVCMTXHF-DATA,
dVCMTXLF-CLK, and dVCMTXHF-CLK.
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.
