PCB design tips for EMI and thermal management in 800G systems

PCB design tips for EMI and thermal management in 800G systems

As the industry accelerates toward 800G Ethernet and optical interconnects, engineers face new challenges in managing electromagnetic interference (EMI) while ensuring signal integrity at unprecedented speeds. The transition to 112G pulse amplitude modulation 4-level (PAM4) SerDes introduces faster edge rates and dense spectral content, elevating the risk of radiated and conducted emissions. Simultaneously, compact module…

Design digital input modules with parallel interface using industrial digital inputs

Industrial digital input chips provide serialized data by default. However, in systems that require real time, low latency, or higher speed, it may be preferable to provide level-translated, real-time logic signals for industrial digital input channel. So, some industrial digital inputs sample and serialize the state of eight 24-V current sinking inputs under SPI or…

Sustainable Web Design: Saving the Planet or Just a Marketing Gimmick?

Sustainable Web Design: Saving the Planet or Just a Marketing Gimmick?

Let’s be real—sustainable web design sounds great in theory. Who wouldn’t want to build a cleaner, greener internet while crafting sleek, high-performance websites? But here’s the thing: most so-called “green” web practices are more about looking good than actually making a difference. Slapping a “carbon-neutral hosting” badge on your site doesn’t erase the fact that…
