Nexperia USA Inc. PCMF2USB3S/S711

Overview

PCMF2USB3S from Nexperia is a dual-channel common-mode EMI filter with integrated ±15 kV IEC 61000-4-2 ESD protection, designed for high-speed differential interfaces including USB 3.2 (10 Gbps), HDMI 2.0, and MIPI D-PHY/CSI. It features 0.3 dB differential insertion loss at 1 MHz, −38 dB common-mode attenuation at 2.6 GHz, and 0.25 pF diode capacitance per line - enabling signal integrity preservation in compact mobile and portable designs.

For engineers reviewing the PCMF2USB3S datasheet, PCMF2USB3S pinout, PCMF2USB3S application, or PCMF2USB3S equivalent, this device serves as a wafer-level chip-scale solution for simultaneous EMI suppression and robust ESD hardening on two independent differential pairs - critical for USB Type-C, display interface, and camera module front-end protection.

Technical Context

The PCMF2USB3S integrates two matched coupled inductors per channel to suppress common-mode noise while maintaining low differential insertion loss (<0.3 dB at 1 MHz) and preserving 6 GHz differential −3 dB bandwidth. Its symmetrical layout ensures <0.1 ps inter-pair skew and <0.25 pF line-to-line capacitance, minimizing signal distortion on 10 Gbps USB 3.2 SuperSpeed lanes.

ESD protection uses snap-back clamping diodes with dynamic resistance of 0.14 Ω (TLP, ±100 ns), delivering 15 kV contact discharge immunity per line without degrading high-frequency performance. Ground terminals B1 and B2 are isolated internally, supporting independent channel grounding for noise isolation in mixed-signal PCB layouts.

Key Specifications

Pinout & Package

PCMF2USB3S uses a 10-bump Wafer-Level Chip-Scale Package (WLCSP10_4-2-4), measuring 1.62 mm × 1.52 mm × 0.60 mm, with solder bumps arranged in three rows (A/B/C) and four columns (1–4). Ground pins B1 and B2 are electrically isolated - allowing separate grounding of Channel 1 and Channel 2 to minimize crosstalk.

FAQ

What is the maximum data rate supported by PCMF2USB3S?

PCMF2USB3S supports up to 10 Gbps differential signaling, validated via USB 3.2 Gen 2 eye diagrams (Fig. 5–6) showing >90% eye height with the device installed. Its 6 GHz differential −3 dB bandwidth and 0.25 pF line capacitance ensure minimal intersymbol interference at full-speed operation.

Can PCMF2USB3S be used for HDMI 2.0 clock lane protection?

Yes - PCMF2USB3S is qualified for HDMI 2.0 TMDS clock lane protection, as confirmed by eye diagram testing at 148.5 MHz (Fig. 9–12). Its symmetric design and low skew (<0.1 ps) preserve clock/data alignment, and its −38 dB common-mode attenuation at 2.6 GHz suppresses radiated emissions from the clock pair.

How should the isolated ground pins B1 and B2 be routed on the PCB?

B1 and B2 must be connected to separate ground planes or split ground regions dedicated to each channel - never tied together on the PCB. This isolation prevents noise coupling between protected lanes. Each ground plane should have low-inductance vias to the main system ground near the device, avoiding daisy-chaining.

Does PCMF2USB3S require external biasing or control signals?

No - PCMF2USB3S is a passive, unpowered device. It requires no external voltage, current, or control logic. All functionality (common-mode filtering and ESD clamping) is inherent to its integrated coil/diode structure and operates transparently in-line with differential signal paths.
