Pcb Routing Guidelines For Ddr4 Memory Devices And Impedance

When designing PCBs for LPDDR4 memory devices, adhering to proper routing guidelines is crucial for ensuring optimal performance and signal integrity. One of the key considerations is maintaining controlled impedance throughout the traces that connect the memory chips. Typically, a differential impedance of 100 ohms is recommended for the data lines, while the command and address lines should be routed with a target impedance of 50 ohms. To achieve this, designers should carefully select trace widths and spacing based on the PCB stack-up and material properties. Additionally, minimizing trace lengths and avoiding sharp bends can help reduce signal degradation and crosstalk. Implementing these routing practices will not only enhance the reliability of the LPDDR4 interface but also contribute to overall system performance.
