Description
- "Time-Card\SOM\FPGA\Readme.pdf" shows that ANT1 and ANT2 are input ports;
However, "Time-Card\ECAD\Beta-V1\USER_IO.SchDoc" shows that ANT1 and ANT2 are output ports;
Futhermore, i can only get 10MHz (from my crystal oscillator) on the 4th pin of the "U8"(NC7SZ125M5), and there is nothing output on all four SMA ports ".
Q1: Could you please explain the contradiction?
- “Time-Card\GNSS\UBX\RCB-F9T\README.md" recommands me to program the GNSS module by the UBX U-Center, but the 9th generation GNSS is not supported for the function of programming by U-Center.
Q2: Is it necessary for me to only get PPS on timecard port?
Q3: Does the RCB-F9T blong to 9th generation GNSS ? If so, How can I resolve it？
Last but not least, all these problems are based on the fact that I did not plug in PCIe, but only the external 12V power supply.
Thank you so much !!!
