The following test requirements are only applicable to products running at 6Gb/s.

TSG-13

– Gen3 Transmit Jitter

This tests measures transmitter jitter for products running at 6Gb/s.The test emulates a Gen3 Compliance
Interconnect Channel (CIC) and measures the random jitter (Rj) before the CIC using an MFTP pattern. Then it
measures the total jitter (Tj) before and after the CIC using MFTP and LBP. The total jitter must be less than the
Rj measured plus 0.34 UI. Values are reported in seconds and unit intervals.

TSG-14

– Gen3 TX Maximum Differential Voltage

This test measures the maximum differential output voltage of the transmitter for products running at 6.0Gb/s. It is
measured using an MFTP pattern. The measurement is a peak to peak measurement of the averaged signal
across 4 UI.

TSG-15

– Gen3 TX Minimum Differential Voltage

This test measures the maximum differential output voltage of the transmitter for products running at 6.0Gb/s. It is
measured using an LBP pattern. The test emulates a Gen3 Compliance Interconnect Channel (CIC) and
generates an eye diagram after the CIC. Then it extrapolates the eye closure at BER 1E-12 using the LeCroy
