Nexperia USA Inc. PCMF3HDMI14SZ

Overview

PCMF3HDMI14SZ from Nexperia is a 3-channel common-mode EMI filter with integrated ESD protection for HDMI 1.4 differential signal paths, featuring ±15 kV IEC 61000-4-2 contact discharge rating, 0.25 pF diode capacitance per line at 1 MHz, and −31.5 dB common-mode insertion loss at 3 GHz. It enables robust high-speed signal integrity in compact mobile display interfaces.

For engineers reviewing the PCMF3HDMI14SZ datasheet, PCMF3HDMI14SZ pinout, PCMF3HDMI14SZ application, or PCMF3HDMI14SZ equivalent, this device is selected for HDMI 1.4 TMDS channel filtering where low differential insertion loss (<0.3 dB at 1 MHz), high common-mode attenuation (>30 dB up to 3 GHz), and sub-0.3 pF line capacitance are critical to preserve eye diagram integrity and meet IEC 61000-4-2 Level 4 ESD immunity.

Technical Context

This device implements three independent differential channels, each with magnetically coupled coils for common-mode rejection and bidirectional ESD clamping diodes per signal line. Its WLCSP15 (6-3-6) package integrates all filtering and protection functions without external components.

It delivers differential-mode insertion loss of ≤0.3 dB at 1 MHz and −6 dB bandwidth exceeding 6 GHz, while achieving common-mode attenuation of −12 dB at 800 MHz, −21.5 dB at 1.7 GHz, and −31.5 dB at 3 GHz - enabling compliance with HDMI 1.4 signal integrity requirements.

FAQ

What is the maximum data rate supported by PCMF3HDMI14SZ?

PCMF3HDMI14SZ supports HDMI 1.4's full 2.25 Gbps per TMDS lane, verified by eye diagram testing at 297 MHz pixel clock (Fig 5). Its −3 dB differential bandwidth exceeds 6 GHz and insertion loss remains ≤0.3 dB at 1 MHz, ensuring signal integrity for high-speed serial links without equalization.

Can PCMF3HDMI14SZ be used for DisplayPort or eSATA interfaces?

Yes - its 3-channel architecture, 6 GHz differential bandwidth, and 0.25 pF line capacitance align with DisplayPort 1.2 (5.4 Gbps) and eSATA (3 Gbps) requirements. Application note section 7 explicitly lists DisplayPort and eSATA as supported interfaces, provided layout follows impedance-controlled routing guidelines.

How does the isolated ground pin configuration affect PCB layout?

The three independent GND pins (B1–B3) must be connected to separate local ground planes beneath each channel to maintain isolation. This prevents common-impedance coupling between TMDS lanes and preserves channel-to-channel skew <0.5 ps - critical for HDMI 1.4 timing budgets.

Is reflow soldering compatible with the WLCSP15 package?

Yes - the WLCSP15 package is qualified for standard lead-free reflow profiles (J-STD-020). Figure 18 provides the recommended solder footprint (2.60 mm × 1.40 mm), stencil aperture (0.40 mm × 0.25 mm), and 0.1 mm stencil thickness to ensure reliable bump wetting and void-free joints.
