SpletThe round-trip latency (Acquisition Board to computer back to Acquisition Board) is around 20 ms. This is sufficient for a variety of experiments involving closed-loop feedback. The main factor for the latency is the buffer size, as bigger buffers mean higher mean and higher variance of latency. This duration can be shortened by changing the ... SpletThe round trip latency of a design is a very important metric. It is measured from the PIPE Rx to the PIPE Tx, going across the physical, link and transaction layers. A typical PCI … Splet22. jul. 2024 · PCIe retimer latency specification. The PCIe specification sets limits for retimer-added latency. In non-SRIS clocking modes, this limit is 64 ns for the data rates from 5GT/s to 32 GT/s and 128 ns for 2.5 GT/s. In SRIS modes, the limit also depends on the maximum packet size and a large table of the limits is provided in the specification. taras w stylu hampton

Depends on what you mean by “connection”. That’s not a term used in the specification. If you’re talking about Link latency (send a packet to receiving that packet on a single Link), this is typically around 100ns+packet time on the wire for a x16 Link. taras witchy ways
