An example of the delay calculation follows, given that:
- Line Rate = 1,228.8 Mb/s
- UI = 813.8 ps
- Transceiver Latency = 150 UI
- Datapath Latency = 100 UI
- Slave CDC FIFO = 160 UI
- Slave Barrel Shift = 16 UI
- Slave Coarse Timer = 340 UI
- Master CDC FIFO = 1,340 UI
- Master Barrel Shift = 13 UI
- Master Coarse Timer = 15,000 UI
Cable Delay = (15000 - (150 + 13 + 100 + 1340) - (340 + 150 + 16 + 100 + 160))/2
Cable Delay = 6,315.5 UI = 5,139.55 ns
