Designing to the New PCI Express 3.0 Equalization Requirements
PCI Express 3.0 increased the supported data rate to 8
Gbps, which effectively doubles the data rate supported by PCI Express 2.0.
While the data rate was increased, no improvement was made to the channels. As
such, an 8 Gbps channel in PCIe 3.0 experiences significantly more loss than one
implemented in PCIe 2.0. To compensate for this increased loss, PCI Express 3.0
specifies enhanced equalization in the PHY with improved TX equalization,
improved RX equalization, and equalization training.
It is critical that
designers who plan to implement PCIe 3.0 understand these equalization changes
and their impacts. After attending this webinar, registrants will
- Why improved levels of equalization are necessary at higher data rates
- Types of equalization enhancements required for optimal performance at 8
- The difference between decision feedback equalization (DFE) and continuous
time linear equalization (CTLE)
- The need for equalization training and adaptability in PCIe 3.0
- The importance of proven interoperability between the PHY and the controller
Who should attend: SoC designers and system architects
