Nexperia USA Inc. PCMF1HDMI2BA-CZ

Overview

PCMF1HDMI2BA-C from Nexperia is a single-channel common-mode EMI filter with integrated bidirectional ESD protection for HDMI 2.1/2.0 differential data lines, featuring ±15 kV IEC 61000-4-2 contact discharge rating, 2.2 Ω typical channel series resistance, 0.3 pF diode capacitance at 1 MHz, and 10 GHz differential -3 dB bandwidth.

For engineers reviewing the PCMF1HDMI2BA-C datasheet, PCMF1HDMI2BA-C pinout, PCMF1HDMI2BA-C application, or PCMF1HDMI2BA-C equivalent, this device serves as a wafer-level chip-scale solution for high-speed interface protection where signal integrity, ESD robustness, and PCB space constraints are critical in mobile and display subsystems.

Technical Context

The PCMF1HDMI2BA-C integrates coupled inductors per differential pair to suppress common-mode noise while preserving differential signal fidelity up to 10 GHz. Its clamping structure delivers snap-back behavior with 0.29 Ω dynamic resistance under TLP stress, enabling low-voltage ESD protection without degrading HDMI 2.1 FRL eye diagrams.

It operates across -40 °C to +125 °C ambient temperature, supports 4 V maximum input voltage, and maintains <100 nA reverse leakage per line at 4 V - ensuring minimal DC loading on high-speed receivers while meeting HDMI 2.1 12 Gbps timing margins.

FAQ

What is the maximum data rate supported by PCMF1HDMI2BA-C?

PCMF1HDMI2BA-C supports HDMI 2.1 Fixed Rate Link (FRL) at 12 Gbps per lane, validated via eye diagram testing up to 12 Gbps with worst-case cable models and no equalizer. Its 10 GHz differential -3 dB bandwidth and 0.3 pF capacitance ensure minimal intersymbol interference and timing jitter on high-speed TMDS/FRL lanes.

How does the snap-back clamping mechanism improve ESD protection?

The snap-back clamping structure achieves 0.29 Ω dynamic resistance under TLP stress, reducing clamping voltage to below 8 V during ±15 kV ESD events. This prevents damage to sensitive HDMI receiver inputs while avoiding latch-up or permanent degradation - unlike conventional diodes that exhibit higher clamping voltages and thermal runaway risk.

Can PCMF1HDMI2BA-C be used on MIPI M-PHY or D-PHY interfaces?

Yes - PCMF1HDMI2BA-C is qualified for MIPI D-PHY v2.5 (up to 2.5 Gbps) and M-PHY HS-Gear3 (up to 5.8 Gbps), with its 2.2 Ω series resistance, 0.3 pF capacitance, and <0.1 Ω line-pair imbalance preserving required skew and jitter budgets. Application note AN11782 confirms layout guidelines for D-PHY CSI-2 integration.

Is GND_CH1 (Pin B1) required to connect to system ground?

Yes - Pin B1 (GND_CH1) must be connected to a low-inductance analog ground plane near the device. It serves as the reference for both ESD clamping and common-mode choke operation. Floating or high-impedance connection degrades common-mode rejection by >15 dB and increases ESD clamping voltage by up to 4 V, violating IEC 61000-4-2 Level 4 compliance.
