Clarification on TX/RX P&N Invert feature support in TSE IP core
Hello, Based on the page below from the GTS Transceiver PHY User Guide: Agilex™ 5 FPGAs and SoCs (version 25.1, “Analog Parameter Options” section), the “Enable TX P&N Invert” and “Enable RX P&N Invert” options are described as preliminary and not supported in hardware: 3.3.11. Analog Parameter Options However, according to the updated page for version 25.1.1, those same features are now marked as supported in hardware: 3.3.11. Analog Parameter Options In the Analog Parameters tab of the Triple-Speed Ethernet (TSE) Intel FPGA IP, these TX/RX P&N Invert options also appear as configurable parameters. Could you please confirm whether these features are expected to function in Quartus Prime Pro 25.1.1 and Quartus Prime Pro 25.3 when used in the TSE IP core? Also, could you please let us know what happens if we enable these P/N inversion options in Quartus 25.1, since the documentation indicates that they are not supported in hardware in that release? Thank you in advance for your help and clarification. Best regards,Solved103Views1like8CommentsRMA for EP4CGX110DF27I7N
Hi @david.chan@intel.com, can you help us with the RMA for below case? Since we need to continue with the analysis to determine the root cause, the unit failed in field with our end customer. I’m attaching the FA from Flex. CPN: N0230475 Flex PN: CIE-N0230475 Intel PN: EP4CGX110DF27I7N Reference U91 Thank you for your collaboration in this matter. The I2C stage with FRU 1 on the motherboard involve U91 component and J15 connector, so continuity between signals I2C was checked but no issues where detected. The J15 and U91 component was checked on X-Ray but no solder issue was detected on component’s spheres. No passives components issues nor solder defects related to the stage. Due to the passive components, PCB issues and solder defects were discarded it means that the U91 component has an electrical damaged and I2C communication between FRU 1 and U91 is not working correctly. The U91 was send to replaced and the unit will be tested in order to completed its RMA process303Views1like0Comments
