Product details
Overview
PCMF2DFN1 from NXP Semiconductors is a 2-channel common-mode EMI filter with integrated ESD protection for high-speed differential interfaces, featuring ±15 kV IEC 61000-4-2 contact discharge rating, 0.6 pF typical diode capacitance per line, and 15 dB common-mode insertion loss at 400 MHz. It is deployed in MIPI D-PHY CSI/DSI camera and display links to suppress RF interference while preserving signal integrity.
For engineers reviewing the PCMF2DFN1 datasheet, PCMF2DFN1 pinout, PCMF2DFN1 application, or PCMF2DFN1 equivalent, key selection criteria include common-mode attenuation bandwidth (up to 5 GHz), differential insertion loss (<0.6 dB at 1 MHz), ultra-low profile (0.5 mm height), and compatibility with 1.5–3.4 Gbit/s data rates in mobile interface designs.
Technical Context
The PCMF2DFN1 integrates coupled inductors per differential channel to provide frequency-selective common-mode rejection while maintaining low differential insertion loss. Its clamping structure exhibits snap-back behavior with dynamic resistance of 0.6 Ω under TLP stress, enabling low clamping voltage (4.8 V positive / −3.6 V negative at 4–5 A).
Each channel uses bidirectional ESD diodes with 6–9 V breakdown voltage and <100 nA reverse leakage at 5 V, operating across −40 °C to +85 °C ambient. The device supports MIPI D-PHY compliance by preserving eye diagram integrity at 1.5 Gbit/s and 3.4 Gbit/s, with differential −3 dB bandwidth up to 2.2 GHz.

Equivalent & Alternatives
The following parts are listed as comparable options for similar common-mode EMI filtering with integrated ESD protection applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TPD2E001DRYR (Texas Instruments) | Single-channel, 0.5 pF capacitance, ±8 kV ESD, no common-mode choke | Limited to point-of-interface protection; lacks broadband common-mode rejection | Select when only ESD protection is needed and board space allows separate choke placement |
| EMIF02-MIC03F2 (STMicroelectronics) | 2-channel, 12 pF capacitance, ±15 kV ESD, no differential bandwidth spec >1 GHz | Higher capacitance degrades >1 Gbit/s signal integrity; unsuitable for MIPI/HDMI | Use only for audio or low-speed USB 2.0 where bandwidth constraints are relaxed |
Compared with TPD2E001DRYR and EMIF02-MIC03F2, PCMF2DFN1 uniquely combines 2-channel differential filtering, 2.2 GHz bandwidth, and ±15 kV ESD in a 0.5 mm-profile DFN - making it the only option validated for MIPI D-PHY CSI/DSI and HDMI mobile links requiring simultaneous noise suppression and signal fidelity.

FAQ
What is the maximum data rate supported by PCMF2DFN1?
PCMF2DFN1 supports differential data rates up to 3.4 Gbit/s, as verified by HDMI eye diagram testing at that rate. Its 2.2 GHz −3 dB differential bandwidth and <0.6 dB insertion loss at 1 MHz ensure minimal jitter and amplitude degradation for MIPI D-PHY v1.2 and HDMI 1.4 applications.
Can PCMF2DFN1 be used for USB 3.0 SuperSpeed signals?
No - PCMF2DFN1 is not specified for USB 3.0 (5 Gbit/s). Its differential −3 dB bandwidth is 2.2 GHz, insufficient for SuperSpeed's 2.5 GHz fundamental frequency. It is qualified for MIPI D-PHY (≤3.4 Gbit/s) and HDMI 1.4 (≤3.4 Gbit/s), but not for protocols requiring >2.5 GHz signal fidelity.
How does the snap-back clamping mechanism improve ESD protection?
The snap-back structure reduces dynamic resistance to 0.6 Ω during ESD transients, lowering clamping voltage to 4.8 V (positive) and −3.6 V (negative) at 4–5 A. This prevents voltage overshoot beyond downstream IC absolute maximum ratings, unlike standard diodes with higher dynamic resistance and clamping voltage.
Is PCMF2DFN1 compliant with automotive AEC-Q200?
No - PCMF2DFN1 is not AEC-Q200 qualified. The datasheet explicitly states it is "non-automotive qualified" and intended for consumer mobile applications (smartphones, tablets, MIDs). For automotive use, NXP offers separate AEC-Q200–qualified ESD filters such as PESDxUSB30 series.
