By Business Wire News


Pulse Electronics Corporation, a leading provider of electronic components, introduces its new family of functional isolation transformers. Pulse’s BX4500LNL and BX4500LNLT transformers can be matched with a Microsemi line driver and used with Broadcom’s BCM652xx DSP and BCM659xx AFE chipsets for transmission, Le87282. Operating bandwidth is 2 MHz to 100 MHz with target speeds up to 1 Gbps to consumer residences. These transformers enable Broadcom’s chipsets to deliver high-speed broadband access for broadcast quality multi-stream IPTV, voice, data, and home networking.

The transformers are built on a very small platform of 8mm x 8mm x 10mm (length x width x height) with a low leakage inductance of less than 0.4 µH. is the newly approved ultra-broadband DSL standard from the ITU for local loops shorter than 500 meters and is expected to deliver up to 1 Gbps to consumer residences, ITU-T G.9701.

“These transformers have improved longitudinal balance and provide excellent total harmonic distortion performance on a very compact platform,” explained Ronan Kelly, product marketing manager, Pulse Electronics. “The series supports Broadcom’s chipset technology to drive data rates up to 150 Mbps/downstream and 100 Mbps/upstream on a single line.”

Pulse Electronics’ BX4500LNL transformer is packaged in trays while the BX4500LNLT is packaged in tape and reel. They are EN60950 functional isolation compliant 250Vrms and RoHS-6 compliant SMD products. The transformers are available now with a lead-time of 8 weeks. Evaluation samples are available immediately. More information can be found on the datasheet located on the Pulse website at, or by contacting Pulse at or visiting the Pulse Electronics website at
