Length matching is required per segment, and any length added (typically a ‘serpentine’ ... An uncoupled section of trace routing into a pin or a ball should be ≥45 mils when using multiple bends, as shown in Figure 5. 2.3 Test points, vias and pads
WebJan 30, 2024 · Differential Pairs Routing - defines the routing width of the nets in the pair, the separation (gap) between the nets in the pair, and the overall uncoupled length (the pair becomes uncoupled when the gap is wider than the Max Gap setting). WebOct 3, 2024 · Avoid the temptation if at all possible. The inter-pair skew can add up to a millimeter which is an order of magnitude more deviation than the application notes generally allow. Balance the left and right bends as much as possible so you’re not exceeding the uncoupled length constraint with too many phase tuning bumps.
