Common-Mode Filters with Integrated TrEOS ESD Protection

Nexperia's new common-mode filters featuring integrated TrEOS ESD protection avoid electromagnetic interference (EMI) of high-speed wired communication standards like USB3.1, HDMI2.0, and MIPI M-PHY with popular mobile frequency bands such as LTE, Wi-Fi, and Bluetooth to enable undisturbed communication. Also available as a standalone ESD protection device in the same footprint allowing last minute changes without PCB redesign for maximum flexibility and shorter design cycles.

There are three key parameters for a perfect ESD protection device:

• High-robustness against ESD pulses
• Low-clamping / dynamic resistance to protect the system chip
• Low-capacitance to maintain excellent signal integrity

While some applications require good performance in only one or two of these areas, for the latest high-speed interfaces, optimum performance in all three parameters is key. Until recently, improving one of these key parameters had a negative impact on the others. Addressing this challenge, NXP has developed a new ESD technology, TrEOS Protection, that  delivers benchmark performance in all three key parameters.

Features

• A technically advanced solution with best RF-performance and common-mode rejection to ensure undisturbed wired and wireless communication and high system-level ESD robustness
• An integrated solution (filters plus ESD protection) to save space and achieve the lowest total cost of design
• Highest flexibility and quick time-to-market with the integrated solution (PCMF with ESD) and standalone ESD protection (PESD) in the same footprint to easily swap without PCB redesign, even if the solution is adapted after product launch

Benefits

• Suitable for numerous high-speed interfaces: USB3.1, HDMI2.0, MIPI, CSI, and DSI
• No ferrite saturation, widest differential pass-band compared to other Si-based solutions and ferrite-based solutions, when adding ESD protection with 14 GHz pass-band to ferrites
• Lowest ESD-clamping compared to all other common mode filters: provides > 15 kV system-level ESD robustness even for the most sensitive USB3.1 transceiver
• Strongest common mode rejection for the USB3.1 fundamentals at 2.5 and 5 GHz of all USB3 common mode filters
• PCMF1USB3S allows very easy RF-routing together with the new USB Type-C connector
• Only available solution for common mode filters and standalone ESD protection in the same footprint
