Can You Use Series and Parallel Termination on the Same Net?

Can You Use Series and Parallel Termination on the Same Net? Series and parallel termination are the most common resistive termination options for digital signaling. The reason is that resistance is a wideband quantity and does not start to be affected by parasitics until well into the GHz range. At the channel bandwidth associated with most digital signals, there are cases where an unterminated line actually needs termination, even if there is no impedance specification in the interface. As both options Read Article

Lossy Transmission Line Impedance Without a Field Solver

How to Use SFP Connectors in Your PCB Layout

How to Use SFP Connectors in Your PCB Layout SFP connectors are used to route data into fiber optic transceiver modules, which are normally found in high-speed networking equipment. Today, however, I’ve had multiple design requests that involve the use of fiber transceivers outside of a data center environment. Newer systems in sensor fusion, MIMO systems, rugged OpenVPX switches, and some industrial robotics need to stream huge amounts of data back to a workstation or server, with data Read Article

6:07 Power Integrity Analysis in Your PCB Design Software Power integrity problems can abound in modern PCBs, especially high-speed boards that run with fast edge rates. These systems require precise design of the PDN impedance to ensure stable power is always delivered throughout the system. Without carefully considering the PDN impedance, you’re at risk of creating ripple and noise in the power distribution network when fast signals switch states. As more signals switch in large ICs, the result is the Watch Video
