Figure 3. Short Circuit Output Current Test Circuit
Figure 4. Definition of Intra-Pair Differential Skew
A. HDMI 1.3 compliant cable when EQ = Low, and 10m 28AWG input cable when EQ = High.
B. All jitters are measured in BER of 10
-9
C. The residual jitter reflects the total jitter measured at the output of the DUT, TP3, subtract the total jitter from the
signal generator, TP1
