Nexperia USA Inc. PCMF1HDMI14SZ

Overview

PCMF1HDMI14SZ from Nexperia is a single-channel common-mode EMI filter with integrated ESD protection for HDMI 1.4 differential signal lines, featuring ±15 kV IEC 61000-4-2 contact discharge rating, 0.25 pF diode capacitance at 1 MHz, and −31.5 dB common-mode insertion loss at 3 GHz. It enables robust high-speed signal integrity in space-constrained mobile display interfaces.

For engineers reviewing the PCMF1HDMI14SZ datasheet, PCMF1HDMI14SZ pinout, PCMF1HDMI14SZ application, or PCMF1HDMI14SZ equivalent, this device serves as a wafer-level chip-scale solution for HDMI TMDS line filtering and downstream ESD clamping - critical for smartphone, tablet, and portable display designs requiring minimal board footprint and guaranteed RF performance.

Technical Context

The PCMF1HDMI14SZ integrates coupled inductors per differential channel to suppress common-mode noise while preserving differential signal integrity up to 6 GHz (−3 dB cutoff), with <0.3 dB differential insertion loss at 1 MHz. Its snapback clamping structure delivers dynamic resistance of 0.16 Ω during ±16 A TLP transients, reducing clamping voltage to ±4 V.

It uses a WLCSP5 (2-1-2) bump layout with separate input/output signal pairs and dedicated channel ground (GND_CH1), enabling clean return path separation. Diode capacitance (0.25 pF) and series resistance (3 Ω per line) are optimized to avoid HDMI 1.4 eye diagram degradation, as verified in application testing with 297 MHz pixel clock signals.

FAQ

What is the maximum HDMI data rate supported by PCMF1HDMI14SZ?

PCMF1HDMI14SZ supports HDMI 1.4's full 10.2 Gbps aggregate bandwidth (3.4 Gbps per TMDS channel), validated via eye diagram testing at 297 MHz pixel clock with 100% opening retention. Its 6 GHz differential −3 dB bandwidth and <0.3 dB insertion loss at 1 MHz ensure compliance with HDMI 1.4 electrical specifications without equalization overhead.

Can PCMF1HDMI14SZ be used with HDMI 2.0 or HDMI 2.1 interfaces?

No - PCMF1HDMI14SZ is characterized and qualified only for HDMI 1.4 (up to 3.4 Gbps per lane). HDMI 2.0 (6 Gbps) and HDMI 2.1 (12+ Gbps) require lower capacitance (<0.15 pF), tighter skew control (<0.05 ps), and broader bandwidth (>12 GHz), which exceed this device's specified performance envelope per Nexperia's published characteristics and application notes.

Is PCMF1HDMI14SZ compatible with standard reflow soldering processes?

Yes - PCMF1HDMI14SZ uses a WLCSP5 package qualified for IPC/JEDEC J-STD-020 moisture sensitivity level 1 (MSL1), supporting peak reflow temperatures up to 260 °C. Recommended stencil aperture is 0.25 mm × 0.25 mm with 0.1 mm thickness, and solder land design follows Nexperia's Figure 16 footprint for optimal void-free attachment and thermal reliability.

Does PCMF1HDMI14SZ require external bias or control signals?

No - PCMF1HDMI14SZ is a passive, unpowered component. It requires no supply voltage, enable pin, or configuration interface. Operation is fully automatic: ESD clamping activates only during transient overvoltage events, and common-mode filtering occurs continuously via integrated magnetics, with zero quiescent power consumption.
