Pulse Electronics Corporation (NYSE: PULS), a leading provider of electronic components, today introduced the HOT ROD product family of I-Bar chokes for automotive networks, a new concept to provide EMC/EMI protection for automotive electronics. The new line of I-Bar HOT ROD chokes are optimized to meet Broadcom Corporation’s BroadR-Reach Automotive Ethernet technology for mode conversion up to 400 MHz. The first part in the series, the AE2000, meets the need for the current generation of 100 Mbps BroadR-Reach automotive Ethernet transceivers.
“The automotive industry has enthusiastically embraced our BroadR-Reach automotive Ethernet technology as the standard in automotive connectivity,” said Nimesh Doshi, Associate Product Line Director, Automotive, Broadcom Corporation. “The addition of Pulse’s AE2000 product to the Automotive Ethernet ecosystem will provide more options to system implementers and help further proliferate Ethernet into a broad range of vehicles.”
The HOT ROD AE20xx family of small-sized (4.5x3.2x2.8mm) SMD components has been approved by the Automotive Electronics Council (AEC) to meet the reliability criteria of AEC-Q200. The AE20xx family of devices is smaller and lighter in weight than Pulse Electronics’ current HM6902NL chokes, used in digital camera networks supporting BroadR-Reach technology. AEC-Q200 is a stringent series of stress and accelerated life testing required by the automotive industry for high reliability components. The AE20xx products are especially suited for use in a confined space. They have an operating temperature range of -40 to +125 oC. A high temperature capability is needed for use particularly on the outside of a vehicle, such as for a camera unit in the fenders, bumpers, and on wing mirrors.
AE20xx chokes are used for noise suppression on Ethernet-based networks transmitting data, video, and voice over a single unshielded twisted pair within a vehicle. These networks can be used for driver-assist applications and equipment combining camera, LiDAR, and sensor feeds like surround or birds-eye camera views, self-parking, blind spot alerts, or collision avoidance as well as infotainment systems combining satellite navigation, phone, audio, and video (DAB, CD, DVD, Internet, and DigitalTV).
