Nexperia launches Common Mode Filter with ESD protection for HDMI2.1 and DisplayPort

Category articles

Nexperia, the specialist in essential semiconductors, has introduced its brand-new PCMFxHDMI2BA-C, a combined, extremely effective, usual setting filter as well as ESD security gadget with the widest 10 GHz differential transmission capacity. It is suitable for the current HDMI 2.1 standard approximately 12G FRL, where eye-diagram examinations were passed despite “worst cable version”.

Stefan Seider, Nexperia’s product supervisor for high-speed security and also filtering system commented: “HDMI 2.1 makes it possible for displays with higher resolution as well as better colours. Nevertheless, this demands greater protection versus disturbance, especially in small wireless applications. The performance as well as miniature dimension of these 2 in 1 combination-devices makes them extremely ideal for ‘tv stick’ type plug-in designs.”

This highly incorporated PCMFxHDMI2BA-C device provides excellent common mode attenuation at HDMI fundamentals: -19.4 dB @ 3 GHz as well as -16 dB @ 6 GHz. ESD efficiency is also excellent with gadgets using a clamping voltage of 7.4 V at 16 A transmission line pulse (5 V at 8 A). TDR resistance dip is < 10 Ohms for 200 ps rise time. The inductance of the coil-pair offers an additional significant reduction of ESD optimal voltages while having a low inductance for differential signals. The parts can secure and filter one, two or three differential line sets, while footprint-compatible ESD protection gadgets without filter are offered.

Along with HDMI 2.1, the mixed common setting filter as well as ESD security devices match various other broadband serial user interfaces consisting of HDMI 2.0, HDMI 1.4, MIPI, DisplayPort.
