Pulse Electronics Corp. recently introduces its new family of G.fast 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 G.fast transmission, Le87282.
The operating bandwidth is 2 MHz to 100 MHz with target speeds up to 1 Gbits/s 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 G.fast 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 AµH. G.fast 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 Gbits/s to consumer residences, ITU-T G.9701.
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 G.fast transformers are available now with a lead-time of 8 weeks. Evaluation samples are available immediately.
