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…

Power Tips #142: A comparison study on a floating voltage tracking power supply for ATE

In order to test multiple ICs simultaneously with different test voltages and currents, semiconductor automatic test equipment (ATE) uses multiple source measurement units (SMUs). Each SMU requires its own independent floating voltage tracking power supply to ensure clean measurements. Figure 1 shows the basic structure of the SMU power supply. The voltage tracking power supplies…

Power Tips # 141: Tips and tricks for achieving wide operating ranges with LLC resonant converters

Inductor-inductor-capacitor (LLC) resonant converters have a couple of appealing characteristics for applications requiring an isolated DC/DC converter such as minimal switching losses, no reverse recovery when operating below the resonant frequency and the ability to tolerate large leakage inductance within the transformer. The challenge A primary challenge when designing an LLC converter with a wide…
