Nexperia USA Inc. PCMF2USB3S/CZ

Overview

PCMF2USB3S from Nexperia is a dual-channel common-mode EMI filter with integrated ESD protection for high-speed differential interfaces. It provides ±15 kV IEC 61000-4-2 contact ESD protection per line, <0.3 dB differential insertion loss at 1 MHz, and −38 dB common-mode attenuation at 2.6 GHz, deployed in USB 3.2 and HDMI 2.0 signal paths to suppress noise while preserving signal integrity.

For engineers reviewing the PCMF2USB3S datasheet, PCMF2USB3S pinout, PCMF2USB3S application, or PCMF2USB3S equivalent, key selection criteria include differential channel count (2), WLCSP10 package footprint, ESD clamping voltage (6–9 V breakdown), common-mode rejection bandwidth (up to 2.6 GHz), and compatibility with 10 Gbps data rates in USB 3.2 Gen 2 systems.

Technical Context

The device integrates two independent differential channels, each with coupled inductors for common-mode suppression and bidirectional ESD diodes on both input and output sides. Its architecture enables simultaneous filtering and protection without compromising differential impedance matching or timing skew.

It operates across −40 °C to +125 °C ambient temperature, supports 5 V DC input voltage, and delivers <0.25 pF diode capacitance per line at 1 MHz - critical for maintaining eye opening in 10 Gbps USB 3.2 and HDMI 2.0 applications as verified in test board eye diagrams.

Key Specifications

Pinout & Package

PCMF2USB3S uses the WLCSP10 (4-2-4) wafer-level chip-scale package, measuring 1.62 mm × 1.52 mm × 0.60 mm max, with 10 solder bumps arranged in three rows (A/B/C) and four columns. The package supports fine-pitch PCB assembly with 0.4 mm bump pitch and requires 0.1 mm stencil thickness for reliable reflow.

FAQ

What is the maximum data rate supported by PCMF2USB3S?

PCMF2USB3S supports 10 Gbps differential data rates, as validated by USB 3.2 Gen 2 eye diagrams (Fig. 5) showing full compliance with jitter and amplitude specifications. Its 6 GHz differential −3 dB bandwidth and <0.3 dB insertion loss at 1 MHz ensure signal integrity through PCIe Gen 3, USB 3.2, and HDMI 2.0 physical layers.

Can PCMF2USB3S be used for HDMI 2.0 applications?

Yes - PCMF2USB3S is explicitly qualified for HDMI 2.0, with test data (Figs. 9–12) confirming improved eye opening at 148.5 MHz TMDS clock frequency. Its low 0.25 pF capacitance and symmetric layout preserve differential impedance, while −38 dB common-mode rejection suppresses radiated emissions from long cable runs.

How does the WLCSP10 package affect PCB layout?

The WLCSP10 (1.62 mm × 1.52 mm) requires precise solder stencil design (0.1 mm thickness, 0.4 mm bump pitch) and strict impedance-controlled routing. Its compact size allows placement directly at USB Type-C or HDMI connectors, minimizing unprotected trace length - critical for passing IEC 61000-4-2 ESD testing without system-level failures.

Is PCMF2USB3S automotive-qualified?

No - PCMF2USB3S is not automotive-qualified per AEC-Q200. While it operates from −40 °C to +125 °C, it lacks automotive-specific reliability testing (e.g., HTOL, TC, UHAST). For automotive infotainment or ADAS applications, Nexperia's automotive-grade equivalents (e.g., PCMF2USB3S/AH) must be specified instead.
