How to reduce crosstalk between power DTU modules?

To reduce crosstalk between DTU modules, increased spacing, shielding, and interface filtering are necessary. Shielded cables should be used for module connections, with the shield grounded at one end. Wiring spacing should be greater than three times the wire diameter, and parallel lengths should be less than 10cm. Ground pins should be placed at connectors to isolate signal pins. A common-mode inductor CML3225A-510T and a TVS diode SMBJ6.5CA should be deployed at the interface. Differential signal transmission should be used, with impedance matching of 100Ω. Through simulation analysis of the crosstalk coefficient, wiring optimization should be implemented to reduce near-end crosstalk (NEXT) to less than -40dB. Measured crosstalk voltage should be less than 5% of the signal amplitude. Reducing crosstalk can improve signal quality by 30% and reduce bit errors.
