Nexperia USA Inc. PCMF2USB3SZ

Overview

PCMF2USB3SZ 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-2. 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 PCMF2USB3SZ datasheet, PCMF2USB3SZ pinout, PCMF2USB3SZ application, or PCMF2USB3SZ equivalent, key selection criteria include differential channel count (2), WLCSP10 package footprint, ESD clamping voltage under TLP (0.14 Ω dynamic resistance), and common-mode rejection performance across 800 MHz–2.6 GHz - all critical for USB Type-C and high-resolution display interface protection.

Technical Context

This device integrates coupled inductors per differential pair to suppress common-mode noise while maintaining low differential insertion loss (<0.3 dB at 1 MHz, −18 dB at 5 GHz). Each channel uses bidirectional ESD diodes with 6 V breakdown voltage and <100 nA reverse leakage at 5 V, enabling robust protection without DC loading.

The WLCSP10 (4-2-4) package places four external input bumps (A1–A4), two isolated ground terminals (B1, B2), and four internal output bumps (C1–C4), supporting independent grounding per channel to minimize inter-channel coupling and preserve impedance matching for >6 GHz differential bandwidth.

Key Specifications

Pinout & Package

PCMF2USB3SZ uses the WLCSP10 (4-2-4) wafer-level chip-scale package: 1.62 mm × 1.52 mm × 0.60 mm body, 10 solder bumps arranged in 3 rows (A/B/C), with no internal connection on B1 and B2 bumps - these serve as isolated thermal/mechanical ground anchors per channel.

FAQ

What is the maximum data rate supported by PCMF2USB3SZ?

PCMF2USB3SZ supports differential data rates up to 10 Gbps, validated via USB 3.2 Gen 2 eye diagram testing (Fig. 5). Its −18 dB insertion loss at 5 GHz and 0.25 pF diode capacitance ensure minimal signal distortion, meeting USB-IF compliance requirements for Gen 2 operation with >60% eye opening margin.

Can PCMF2USB3SZ be used for HDMI 2.0 applications?

Yes - PCMF2USB3SZ is explicitly qualified for HDMI 2.0, with measured eye diagrams showing improved opening at TP1 and TP2 test points (Figs. 9–12). Its −38 dB common-mode attenuation at 2.6 GHz suppresses TMDS-related RFI, and its 0.3 dB differential loss at 1 MHz preserves low-frequency timing margins required for HDMI clock recovery.

How does the isolated ground (B1/B2) improve performance?

The isolated GND_CH1 and GND_CH2 terminals prevent shared-impedance coupling between differential channels, reducing crosstalk by >20 dB (Fig. 3). This isolation maintains independent return paths for each channel, preserving characteristic impedance (85 Ω typical, Fig. 4) and enabling simultaneous protection of unrelated interfaces like USB and DisplayPort without mutual interference.

Is PCMF2USB3SZ compatible with automated optical inspection (AOI) after reflow?

Yes - the WLCSP10 package uses standard solder bump geometry and coplanarity compliant with IPC-7351 Class B. Its 0.25 mm bump pitch and 0.31 mm bump diameter (per Fig. 25) are fully compatible with AOI systems calibrated for wafer-level packages, and the marking code "PF2S" (Table 4) provides unambiguous post-reflow identification.
