Datasheet

Compliant for use with the Lantiq Vinax V3 chipset family, the BX4289LNL and BX4289LNLT signals the expansion of Pulse Electronic's series of transformers. The Class H line driver VDSL2 30MHz vectored transformer is used with the BX4289LNL and BX4289LNLT to deliver high bandwidth over existing copper transmission lines.

The transformers feature improved longitudinal balance and provide excellent total harmonic distortion performance on a very compact platform. Where the copper infrastructure is already available, the BX4289LNL supports the Lantiq chipset technology to drive data rates up to 150 Mbps/downstream and 100 Mbps/upstream on a single line, supporting such services as HD IPTV, high-speed Internet access, multi-player gaming networks, and VoIP.

The BX4289LNL transformer is packaged in trays, while the BX4289LNLT is packaged in tape and reel. They are EN60950 functional, isolation compliant, -250Vrms and RoHS-6 compliant SMD products. They are available now with a lead-time of 8 weeks. Evaluation samples are available immediately.

"VDSL2 has the potential to reach 100 Mbps, but noise among the lines in a cable impedes performance," explained Ronan Kelly, Pulse Electronics broadband product manager. "VDSL2 vectoring cuts out all of the noise, or interference, among the VDSL2 lines in a bundle, so every line within a bundle can operate at peak performance, as if no other VDSL2 lines are present. This results in superior performance and enables copper to reach its full potential, providing a solution for the continuing demand for higher bandwidth."
