Chiplet design basics for engineers

The world is experiencing an insatiable and rapidly growing demand for artificial intelligence (AI) and high-performance computing (HPC) applications. Breakthroughs in machine learning, data analytics, and the need for faster processing across all industries fuel this surge. Application-specific integrated circuits (ASICs), typically implemented as system-on-chip (SoC) devices, are central to today’s AI and HPC solutions….

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…
