CMF with ESD protection for high-speed data communication lines

Integrated
common mode
filter & protection
solving EMI &electrostaticchallenges
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 withelectrostatic 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.xBenefits› Effective 1, 2 & 3 line pairs protection and filtering› USB 3.x & 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 resistanceusing TrEOS technology

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 & 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 & space-saving WLCSP packages› Footprint-compatible with ESD-only solutions› Exceeding IEC 61000-4-2 ESD ruggedness standard

PCMF - Performance advantage thanks to integration
Nexperia’s PCMF series integrate ESD protection and CMF ina single device which offers an unmatched overall performance.
When comparing a standalone CMF solution to a combinationof 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 ofmore 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 athigher signal frequencies.
