ContributorArial10 VCCT_GXB and VCCR_GXB Voltage should be 1.03V for PCIe 3.0?
Hello ,
Answer to your first question : Yes , data rate in datasheet is for each late , here is the Intel Arria 10 transceiver phy guide: Section "Transceiver PHY Architecture Overview"
here is the link for your reference
Answer to your second questions , Yes , you can very well use as long as power consumption is not concern for your application. Keeping at 1.03 V also help to upgrade the data rate in future as per datasheet.
Thank you ,
Frequent ContributorAs you mentioned PCIE 3.0 is max datarate is 8 GT/s . Per datasheet if your application is chip to chip , then both Transmitter / Receiver voltage is 0.95V Typical, but if the your application using backplane or datarate > 11.3 Gbps then the voltage is 1.03V.
A10 datasheet Table 4 clearly indicate that VCC_GXB & VCCR_GXB should be 0.95V when datarate is < 11.3 Gbps.
Thank you
