Integrated EMI Filter for Automotive Ethernet Connectivity
STMicroelectronics' new EMIF02-01OABRY is a highly-integrated solution designed to suppress EMI noise in automotive applications employing BroadR-Reach® interfaces. This EMI-suppressing low-pass filter includes 15kV ISO 10605 surge protection and is AEC-Q101 qualified. Until now, designers have used discrete components to design EMI filters that are compatible with the BroadR-Reach specification. Because there may be a large dispersion between components, these discrete networks' performance must be fine-tuned at significant time and cost.
The EMIF02-01OABRY solves this issue by providing an already application-validated integrated solution, making the end applications smaller and faster to design. Within the Automotive temperature range of -40 to +125 degrees C, the EMI filter attenuation profile is fully compliant with BroadR-Reach requirements, with a return loss of -20dB at 60MHz and component matching of 1% between line 1 and 2.
Other key technical features include: Compliant with the IEC 61000-4-2, ISO 10605, and ISO 7637-3 automotive standards; and Compact 3x3mm wettable-flank QFN package, facilitating optical inspection of the solder joints. Samples of the EMIF02-01OABRY are available now at a price of US$0.48 in quantities of 1000 units.
