Maybe we would warm-restart PC to tigger re-enumerate, but when during PC shutdown and restart interval, the PCIe_REF_CLK will surely disappear, then FPGA XCVR might stop working as a result of lost REFCLK…..it seem to be a desperate loop….or...
As to check on the TTK, you can cross check with your register dump and compare them with the table 277 and 278 in A10 XCVR PHY user guide to see if can match any of the combination for pre/post CDR. Please let me know if there is any concern. Thank you. ...
To interface the MCU to the SAN network, an ST Microelectronics ST3485EB 3.3 V low power transceiver (XCVR) for RS-485 and RS-422 communications is used. A mesh of passive components is used to interface theXCVRto the SAN network: two 10 f F capacitors are used to capacitively couple ...
Router(config-xcvr-type)#monitoring Router(config-xcvr-type)#end When DOM is globally enabled, you can further manage the system at each port. When you want to view the datasheet, the #show interfaces transceiver command will tell the console to display all available information. This is how...
This is also to ensure that XCVR blocks will operate as expected at the new data rates", can I say that if FPGA is not successfully calibrated / re-calibrated, XCVRs can still run, but may with lower performance than it should be? If you are convenient, would you li...
Just to add on, the important thing to take note to ensure compatibility between the FPGA XCVR with PCML IO standard with another device is to make sure the XCVR input and output specs are met. For example, for SV, I can find the specs in Table 23. Transceiver Specifications for Stratix...
What would happen if Transceiver Calibration fails? As Intel UG-01143 chapter 7 (page575) writes, "Transceivers include both analog and digital blocks that require calibration to compensate for process, voltage, and temperature (PVT) variations". For example, Suppose ...
