Learn how to calculate the number of signal wires in a PCIe device with 8 lanes.
A PCIe device with 8 lanes has how many signal wires?
A PCIe device with 8 lanes has 64 signal wires. Each PCIe lane consists of 1 transmit (TX) pair and 1 receive (RX) pair, and each pair has 2 signal wires (1 for sending data and 1 for receiving data). Therefore, 8 lanes would have 8 (lanes) x 2 (TX and RX pairs per lane) x 2 (signal wires per pair) = 64 signal wires.
python Copy code
lanes = 8
signal_wires = lanes * 2 * 2
print(signal_wires) # Output: 64
