Nexperia USA Inc. PCMF3HDMI2BA-CZ

Overview

PCMF3HDMI2BA-CZ from Nexperia is a 3-channel common-mode EMI filter with integrated bidirectional ESD protection for HDMI 2.1/2.0/1.4 differential data lines, featuring ±15 kV IEC 61000-4-2 contact discharge rating, 10 GHz differential -3 dB bandwidth, 2.2 Ω typical channel series resistance, and WLCSP15 (6-3-6) package for mobile display interface protection.

For engineers reviewing the PCMF3HDMI2BA-CZ datasheet, PCMF3HDMI2BA-CZ pinout, PCMF3HDMI2BA-CZ application, or PCMF3HDMI2BA-CZ equivalent, this device supports high-fidelity signal integrity in space-constrained HDMI 2.1 FRL and TMDS channels while delivering robust system-level ESD immunity without degrading differential impedance matching.

Technical Context

This device integrates three independent differential channel filters, each with magnetically coupled coils for common-mode rejection and low-capacitance diodes (0.3 pF @ 1 MHz) for ESD clamping. Its snap-back clamping structure achieves 0.29 Ω dynamic resistance under TLP stress, enabling low-voltage clamping during ±15 kV ESD events.

The WLCSP15 package maintains extreme symmetry between line pairs (<0.1 ps skew), supports 85 Ω differential impedance per channel, and delivers >40 dB common-mode attenuation above 100 MHz - critical for HDMI 2.1 12 Gbps FRL eye opening preservation.

Key Specifications

Pinout & Package

PCMF3HDMI2BA-CZ uses a 15-bump Wafer-Level Chip-Scale Package (WLCSP15) with 6-3-6 bump arrangement, 0.4 mm pitch, and 2.42 mm × 1.22 mm body size. Ground bumps (B1–B3) are isolated from internal circuitry per datasheet Figure 19.

FAQ

What is the maximum data rate supported by PCMF3HDMI2BA-CZ?

PCMF3HDMI2BA-CZ supports HDMI 2.1 Full Rate Link (FRL) at 12 Gbps per lane, validated via eye diagram testing (Fig. 5–8). Its 10 GHz differential -3 dB bandwidth and 0.3 pF diode capacitance ensure minimal intersymbol interference and jitter accumulation at 12 Gbps, meeting HDMI Forum electrical compliance thresholds.

Can PCMF3HDMI2BA-CZ be used for USB Type-C Alternate Mode HDMI?

Yes - PCMF3HDMI2BA-CZ protects three differential HDMI lanes (TMDS Clock, Data0, Data1) found in USB-C Alt Mode implementations. Its 3-channel architecture matches the minimum HDMI lane count required for 4K60 operation, and its WLCSP15 footprint aligns with tight USB-C port PCB layouts.

How does the snap-back clamping behavior affect PCB layout?

The snap-back structure requires avoiding DC bias or unlimited current sources on protected lines, as sustained conduction post-ESD could damage the device. Layout must ensure no direct connection to battery rails or LDO outputs; signal lines must be AC-coupled or current-limited per datasheet Section 9 guidance.

Is PCMF3HDMI2BA-CZ compatible with automated optical inspection (AOI) after reflow?

Yes - the WLCSP15 package uses standard solder land dimensions (0.25 mm × 0.25 mm bumps) and 0.1 mm stencil thickness per Fig. 22, enabling reliable AOI detection of solder joint quality. The absence of wire bonds and uniform bump height improves reflectivity consistency for machine vision systems.
