Summary

PCI-SIG’s PCIe 6.0 standard switched from NRZ to PAM4 to handle 64 GT/s. At the speed, the intra-pair skew between the differential signals becomes very critical. This type of high-speed backplane and interconnect needs to minimize eye margin as this can have a huge impact on errors in the data transmission.

This webinar presents a unique test capability of intra-skew including a practical method to characterize the skew versus BER (Bit Error Ratio). It also highlights a novel and reliable method for introducing granular intra-pair skew into the channel and measuring the impact of BER.
