MIPI走线规范

引言

硬件项目中如果对MIPI走线规范不太清楚的话，可以参考以下MIPI协议里面描述的规范

MIPI Route
Route the three pairs of MIPI signal traces in differential mode. Ensure that the signal traces in
each differential trace pair have the same length, the length deviation of each pair of differential
signal traces fall within ± 5 mils, the length deviation between two pairs of differential signal traces fall within ± 100 mils based on the clock signal, and the impedance of each differential signal trace fall within 100 Ω± 10%. Route the data traces by referring to complete GND planes, and do not cross the plane splits. Ensure that the spacing between adjacent traces meets the 3W rule.

MIPI走线

3对走线都需要走差分模式。确保每个差分对的走线长度相同，每个差分对的走线长度差异保持在± 5 mils以内，每组信号差分对可以相对时钟差分对有± 100 mils的长度差异，同时每对走线的阻抗需要落在100 Ω± 10%以内。信号差分对需要参考完整的地平面，不要有分割。每对差分对尽量符合3W原则。
