Product details
Overview
PCMF3DFN1 from NXP Semiconductors is a 3-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 designed for MIPI D-PHY CSI/DSI lanes in camera and display modules where low signal distortion and robust transient suppression are critical.
For engineers reviewing the PCMF3DFN1 datasheet, PCMF3DFN1 pinout, PCMF3DFN1 application, or PCMF3DFN1 equivalent, key selection criteria include channel count (3), ultra-low profile (0.5 mm height), differential insertion loss <0.6 dB at 1 MHz, common-mode attenuation >30 dB at 800 MHz, and ESD clamping voltage ≤4.8 V (positive) / ≥−3.6 V (negative) at 4–5 A surge.
Technical Context
The PCMF3DFN1 integrates three independent differential channels, each with magnetically coupled coils for common-mode rejection and bidirectional ESD diodes per signal line. Its snap-back clamping structure delivers dynamic resistance of 0.6 Ω during TLP transients, enabling low-voltage clamping without sustained conduction.
It operates across −40 °C to +85 °C ambient, supports data rates up to 3.4 Gbit/s (HDMI) and 1.5 Gbit/s (MIPI D-PHY), and maintains differential-mode bandwidth up to 2.2 GHz (−3 dB point), ensuring minimal eye diagram degradation in high-speed serial links.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Channels | 3 independent differential channels, each with dedicated IN+/IN− and OUT+/OUT− paths |
| ESD Rating | ±15 kV contact discharge (IEC 61000-4-2 Level 4), protecting all input pins against system-level ESD events |
| Common-mode IL | 30 dB attenuation at 800 MHz - suppresses RF noise coupling on shared return paths in flex cable assemblies |
| Differential IL | 0.6 dB at 1 MHz; <0.8 dB up to 1 GHz - preserves signal integrity for MIPI D-PHY and HDMI timing margins |
| Diode Capacitance | 0.6 pF typical per line at 1 MHz/2.5 V - minimizes loading on high-speed differential pairs |
| Clamping Voltage | +4.8 V / −3.6 V at 4–5 A surge (IEC 61000-4-5) - limits downstream IC stress below logic supply rails |
| Package | DFN4020-14 (SOT1334-1), 2.0 × 4.0 × 0.5 mm body - enables placement on tight-pitch flex-to-PCB interconnects |
Pinout & Package
PCMF3DFN1 uses the DFN4020-14 (SOT1334-1) package: 2.0 mm × 4.0 mm × 0.5 mm body, 14-terminal no-lead plastic outline with exposed thermal pad. Pin numbering follows top-view clockwise sequence starting from top-left corner (pin 1).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | CH1_IN+ | Differential input positive for channel 1 - connects directly to SoC-side D0_P or CLK_P trace |
| 2 | CH1_IN− | Differential input negative for channel 1 - routed with matched length and impedance to CH1_IN+ |
| 3 | GND_1 | First ground terminal - provides local return path for channel 1 ESD current and coil coupling reference |
| 4 | CH2_IN+ | Differential input positive for channel 2 - used for D1_P or second clock lane in multi-lane MIPI |
| 5 | CH2_IN− | Differential input negative for channel 2 - maintains 100 Ω differential impedance with CH2_IN+ |
| 6 | GND_2 | Second ground terminal - isolates channel 2 return from channel 1 to prevent crosstalk via shared ground impedance |
| 7 | CH3_IN+ | Differential input positive for channel 3 - supports third MIPI lane (e.g., D2_P) or auxiliary HDMI data pair |
| 8 | CH3_IN− | Differential input negative for channel 3 - completes third differential path with controlled skew vs. other channels |
| 9 | CH3_OUT− | Differential output negative for channel 3 - routes to display/camera module side with minimal stub length |
| 10 | CH3_OUT+ | Differential output positive for channel 3 - paired with CH3_OUT− to preserve common-mode rejection at load end |
| 11 | CH2_OUT− | Differential output negative for channel 2 - terminates at module connector with impedance-matched layout |
| 12 | CH2_OUT+ | Differential output positive for channel 2 - maintains phase alignment with CH2_OUT− for timing-critical D-PHY |
| 13 | CH1_OUT− | Differential output negative for channel 1 - connects to camera sensor or LCD panel input with <1 mm stub |
| 14 | CH1_OUT+ | Differential output positive for channel 1 - delivers filtered, ESD-protected signal to downstream receiver |

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 |
|---|---|---|---|
| TPD4E05U06DQAR | 4-channel, 0.5 pF capacitance, ±12 kV ESD, DQFN-10 package (2.5 × 1.0 mm) | Higher channel density but only 2.5 mm width - unsuitable for 4-mm-wide MIPI DSI flex routing; lacks third channel for full 3-lane support | Select when board space is constrained laterally and only 2 differential lanes require protection |
| EMIF06-MIPI02F3 | 3-channel, 0.35 pF capacitance, ±15 kV ESD, DFN3020-10 package (3.0 × 2.0 mm) | Smaller footprint but only 10 pins - uses shared ground and combined I/O, reducing isolation between channels vs. PCMF3DFN1's dual GND and full I/O separation | Select when lower capacitance is prioritized over channel independence and ground noise isolation |
Compared with TPD4E05U06DQAR and EMIF06-MIPI02F3, PCMF3DFN1 uniquely provides three fully isolated differential channels with dedicated ground terminals and optimized 4.0 mm width matching standard MIPI DSI flex width, making it the only option supporting full 3-lane timing integrity and ESD robustness in space-constrained mobile display designs.

FAQ
What is the maximum data rate supported by PCMF3DFN1 without signal degradation?
PCMF3DFN1 supports differential data rates up to 3.4 Gbit/s, validated via HDMI eye diagram testing (Fig 10) and MIPI D-PHY 1.5 Gbit/s compliance (Fig 9). Its 2.2 GHz −3 dB differential bandwidth and <0.6 dB insertion loss at 1 GHz ensure minimal jitter accumulation and eye closure in production systems.
Can PCMF3DFN1 be used for USB 3.0 differential pairs?
No - PCMF3DFN1 is not rated for USB 3.0 SuperSpeed (5 Gbit/s). Its differential −3 dB bandwidth is 2.2 GHz, insufficient for 2.5 GHz fundamental frequency of USB 3.0; insertion loss exceeds 1.2 dB at 2 GHz, violating USB 3.0 channel loss budget. It is qualified only for MIPI D-PHY (≤1.5 Gbit/s), HDMI 1.4 (≤3.4 Gbit/s), and similar interfaces.
How does the dual-ground (GND_1/GND_2) configuration improve noise rejection?
GND_1 and GND_2 provide separate low-impedance return paths for channel 1 and channel 2, preventing magnetic coupling and ground-bounce crosstalk between adjacent differential lanes. This isolation maintains >30 dB common-mode rejection across all three channels simultaneously, critical for multi-lane MIPI interfaces where inter-lane skew must stay <0.2 UI.
Is PCMF3DFN1 compliant with automotive AEC-Q200 requirements?
No - PCMF3DFN1 is specified for commercial temperature range (−40 °C to +85 °C) and carries no AEC-Q200 qualification. NXP explicitly states in Section 11.3 that non-automotive qualified products like PCMF3DFN1 are not tested to automotive reliability or environmental stress standards and must not be used in safety-critical vehicle systems.
