Nexperia USA Inc. PCMF2HDMI14SZ

Overview

PCMF2HDMI14SZ from Nexperia is a dual-channel common-mode EMI filter with integrated ESD protection for HDMI 1.4 TMDS differential pairs, featuring ±15 kV IEC 61000-4-2 contact discharge rating, 0.3 dB differential insertion loss at 1 MHz, and −31.5 dB common-mode attenuation at 3 GHz. It operates across −40 °C to +85 °C ambient and uses WLCSP10 (4-2-4) packaging for compact mobile interface protection.

For engineers reviewing the PCMF2HDMI14SZ datasheet, PCMF2HDMI14SZ pinout, PCMF2HDMI14SZ application, or PCMF2HDMI14SZ equivalent, this device is selected for high-fidelity HDMI signal integrity preservation while meeting stringent system-level ESD immunity requirements in space-constrained portable designs.

Technical Context

The device integrates two matched differential channels, each with coupled inductors for common-mode rejection and low-capacitance ESD diodes (0.25 pF @ 1 MHz, 2.5 V) for signal-line protection. Its clamping voltage is −3.7 V at −16 A TLP, enabled by snapback-triggered negative dynamic resistance (0.16 Ω).

Designed for HDMI 1.4's 297 MHz pixel clock, it maintains differential impedance stability (Z_dif ≈ 100 Ω) and delivers >6 GHz −3 dB differential bandwidth while suppressing common-mode noise across 800 MHz–3 GHz - critical for passing HDMI compliance eye tests with minimal jitter impact.

FAQ

What is the maximum data rate supported by PCMF2HDMI14SZ?

PCMF2HDMI14SZ supports HDMI 1.4 data rates up to 2.25 Gbps per lane, validated by eye diagram testing at 297 MHz pixel clock (Fig 5). Its 6 GHz differential −3 dB bandwidth and <0.3 dB insertion loss at 1 GHz ensure minimal intersymbol interference and jitter accumulation in TMDS signaling.

Can PCMF2HDMI14SZ be used for DisplayPort 1.2 applications?

Yes - PCMF2HDMI14SZ meets DisplayPort 1.2 requirements for dual-lane protection, with 0.25 pF diode capacitance preserving signal integrity at 5.4 Gbps, and −21.5 dB common-mode attenuation at 1.7 GHz matching DP's primary noise band. Its WLCSP10 footprint allows direct placement near DP source connectors.

How does the snapback behavior affect system reliability during ESD events?

The snapback-triggered negative dynamic resistance (0.16 Ω) reduces clamping voltage to −3.7 V at −16 A TLP, limiting stress on downstream HDMI PHYs. However, sustained DC overvoltage (>9 V) must be avoided to prevent latch-up; the device is intended for transient ESD only, not continuous overvoltage conditions.

Is PCB layout guidance available for optimal common-mode rejection?

Yes - maintain matched trace lengths and 100 Ω differential impedance for all IN+/IN− and OUT+/OUT− pairs; place the device within 3 mm of the HDMI connector; use separate GND_CH1/GND_CH2 pours tied at a single point near the device; avoid routing other signals under the WLCSP10 body to preserve symmetry and minimize parasitic coupling.
