Helo my frends
i am making a customiser PCB and i what to conecct a camera IMX335 direct to the pines from the stm32N6, but i donot know if it is posible?
Could that direct camera connection to the STM324 work without the ECMF2-40A100N6?

Its risky, it can permanently damage your circuit from electrostatic discharge (ESD) or electrical transients. If you still want to do it, I would recommend you to use ECMF2-40A100N6 or any other of its kind.

Short answer: you can’t wire an IMX335 straight to STM32 pins.
Why: IMX335 outputs MIPI CSI-2 only. Most STM32 parts (including STM32N6/STM32F4/H7 families) expose DCMI (parallel DVP) or no camera interface at all—so the electrical/physical layer doesn’t match.
What you need instead:
Use a MIPI-CSI2 to parallel (DVP) bridge (e.g., Toshiba TC358746, Lattice CrossLink, or an ISP like ON Semiconductor AP1302), or
Pick a sensor with parallel DVP output (e.g., OV5640 DVP) that matches STM32’s DCMI.
About the ECMF2-40A100N6:
That part is an ESD/EMI common-mode filter for high-speed MIPI lanes. The link might “work” on a lab bench without it, but you risk ESD damage, EMI issues, and signal integrity problems. For a reliable design, include proper ESD/EMI protection (like ECMF2 or equivalent), 100-Ω differential routing, tight pair matching, correct power sequencing, and the control bus (I²C) level matching.
Summary:
Direct connection = not feasible. Use a MIPI-to-DVP bridge (or a DVP sensor), and keep the ESD/EMI filter in the design for robustness.
