High-speed PCB designs are advancing transmission rates but face challenges with declining anti-interference capability due to increased signal sensitivity and reduced energy, necessitating effective shielding against both low-frequency electromagnetic interference (EMI) and high-frequency radio frequency interference (RFI) to ensure signal integrity and prevent data interception.
The design of LVDS signals on PCB boards involves managing both differential and high-speed digital signals. Whether using PCB traces or cables for LVDS transmission, it’s crucial to prevent signal reflections at the media terminal and reduce electromagnetic interference to maintain signal integrity. Careful wiring considerations make designing high-speed differential circuit boards manageable. Key design considerations include layout on multilayer boards with a ground layer adjacent to LVDS signal layers for interference shielding, and precise impedance calculation and control to minimize signal degradation from reflected signals in transmission lines, typically maintaining differential impedance at 100 +/- 10Ω.
Creating a PCB involves translating a schematic into a physical board, posing practical challenges despite theoretical feasibility, particularly in handling high-frequency and weak signals, requiring meticulous design for consistent high quality.
