Common Mode Filter (CMF) with ESD protection for high-speed data communication lines
High-speed wired lines and popular wireless standards frequently interfere in the Gigahertz range, resulting in EMI disturbance for mobile users. Nexperia has designed common mode filters with electrostatic discharge protection for 1, 2 and 3 differential line pairs that attenuate common mode signals and deliver superior communications experiences.
Our solutions provide common mode noise suppression over all bands, with high suppression at 2.5 GHz and 5 GHz, the fundamentals of USB 3.x
Common Mode Filter lets differential signals pass and attenuates common-mode noise
Features
- Protection up to 6 lines (Tx +/-, Rx +/-, D +/-)
- Wide differential passband (up to 10 GHz 3dB frequency)
- Up to -32 dB CM rejection at 2.5 GHz and up to -21 dB at 5 GHz (USB3 fundamentals)
- Up to -31 dB CM rejection at 3 GHz and -16 dB at 6 GHz HDMI fundamental
- Suitable for HDMI2.1 @ 12 GHz FRL
- Low-inductance and space-saving WLCSP packages
- Footprint-compatible with ESD-only solutions
- Exceeding IEC 61000-4-2 ESD ruggedness standard
Benefits
- Effective 1, 2 and 3 line pairs protection and filtering
- USB 3.x and HDMI2 optimized common mode suppression
- Proven 10+ Gbps communications lines protection
- Providing high system-level robustness for sensitive SoCs
- Minimized reflections compared to discrete CMF + additional ESD
- Low clamping and dynamic resistance using TrEOS technology
PCMF - Performance advantage thanks to integration
Nexperia’s PCMF series integrate ESD protection and CMF in a single device which offers an unmatched overall performance. When comparing a standalone CMF solution to a combination of discrete CMF and discrete 14 GHz differential pass band ESD protection, performance losses are notable.
In contrast to this, our PCMFxUSB3B and ...BA deliver a performance advantage of more than 1 GHz and even 3 GHz compared to the standalone CMF without ESD protection. The maximum of the Common Mode Rejection is shifting as well to attenuate CM noise at higher signal frequencies.
