Table 25: DSI Data Rate and PCB Maximum Trace Length (D-PHY)
1.
The flex cable length used in this table is an example with specified insertion loss
.
2.
The flex cable insertion loss can be measured using a vector signal analyzer or obtained from the flex
cable datasheet. Cable insertion loss on the design should be no worse than what is listed above.
3.
The maximum PCB trace length listed above includes the length routed inside the module.
