Do P/N matter for Diff Pair Clock Inputs to FPGA?
I have noticed on a schematic for an FMC card that the differential pairs of a differential LVDS oscillator do not match the corresponding FPGA transceiver reference clock pins. I.e. the P/N are ...

Can transceiver replace SPI, I2C and other "normal" methods for high speed data transfer between FPGAs? If so, how? [closed]
SPI, I2C and UART are some well known serial methods for data transfer between devices on the same PCB. However, they all have a data rate bottleneck which is significantly lower than Multi Gigabit ...

Gigabit transceiver with MHz reference clock
I've some experience with Xilinx FPGA generating 10Gb/s over SMA loopback with on-off keying modulation (what scope shows) to perform BER test but the documentation shows it uses a reference clock in ...

Data Transfer without Transceiver on FPGA
While going through the transceiver component on an FPGA, I realized that data transfer can take place without transceivers as well, although the speed would reduce or in other words, as tasks ...

How can a transceiver pin be used if its clock is so much faster than the FPGA clock?
I'm trying to understand how a transceiver pin can actually operate at, say, 2.5GHz given that the clock speed of an FPGA is so much slower. In my understanding, to transmit data you need to ...
