Nexperia’s PCMFxUSB3BA/C is presented as the fastest common-mode filter (choke)/ ESD protection combination available, with a differential passband of up to 10 GHz at 3dB frequency, and a surge robustness of up to 7.5 A at 8/20 µs. Designed to suppress common mode and single-ended noise while minimizing the impact on the signal integrity of extremely fast data lines, the devices provide effective 1, 2 & 3 line pair protection (Tx +/-, Rx +/-, D +/-) and filtering.
Proven for 10 Gbps communications line protection, the filter’s system-level robustness exceeds IEC 61000-4-2 level 4, suitable for use with sensitive SoCs. The solution also minimizes reflections when compared to a discrete design. The integration of Nexperia’s TrEOS technology results in low clamping and high robustness. The PCMF filters come in low-inductance, space-saving WLCSP packages, and are footprint-compatible with available ESD-only solutions for fast design changes.
