Recommended Stackup and Impedance Design for RK3588 PCB

Recommended Stackup and Impedance Design for RK3588 PCB

To reduce the reflection phenomenon during high-speed signal transmission, it is necessary to maintain impedance matching at the signal source, receiving end, and transmission line. The specific impedance of a single-ended signal line depends on its line width and its relative position to the reference plane. The line width/spacing of differential pairs with specific impedance … Read more
