Contributorfpga core and fpga transceiver use the same voltage source
Hi,
Now we have one board that its core and transceiver use the same voltage source:
FPGA TYPE : 10ax115n2f45i2sg
pre chage this voltage (about 0.9v), use 4 simplex tx transceiver and 4 simplex rx transceiver.
when we do the transceiver prj, the transceiver could not work normally;
after chage this voltage (about 1.03v), use 8 simplex tx transceiver and 8 simplex rx transceiver.
when we do the transceiver prj, the transceiver could work normally;
I want to know, if we use this supply method for fpga core( exceed its typical voltage from datasheet), will it effect the fpga core logic function? If yes, is there any suggestion for this voltage level when use this board?
Brs,
Lambert
