PCIe 4.0? Naw, We Want The Phison PCIe 5.0 Redriver IC PS7101

Apply Signal Enhancement, And Reduce The Noise On That Data

PCIe 4.0 looks to be one of the shorter lived data transfer interfaces as both AMD and Intel are working on implementing it in the not too distant future and Phison is ready for them.  Phison just announced their PS7101, a PCIe 5.0 Redriver IC which overcomes the problems presented by this high speed interface.  A single PCIe 5.0 lane offers 32Gbps per second, twice that of PCIe 4.0 and at that transmission speed signal attenuation and noise present a serious challenge.

The new Phison PCIe 5.0 PS7101 IC is designed to reduce the signal reflection and crosstalk interference introduced as data passes through your motherboard traces or server riser card, as well as helping to dissipate the heat produced from said transfers.  It is not just a black box either, the Phison PS7101 can be modified by vendors to best perform on their specific platforms.  This means a motherboard vendor is able to use Phison’s Auto Tuning Tool to monitor PCIe 5.0 signals, and feed that data into ye olde AI device to determine the required tweaks for their specific design.  

The PCIe 5.0 Redriver and Retimer IC is not strictly a Phison standard either, it was developed by a partnership of companies so we don’t have to worry about a complete monopoly as of yet.  PCIe 5.0 ICs and controllers will arrive before motherboard vendors are ready for them; a good thing as Phison and others are already hammering out the bugs for the arrival of PCIe 6.0.
