Of course, Intel is not the only 10 GbE game in town. For example, Broadcom manufactures an extensive range of 10 GbE PHYs for backplane, optical, serializer/deserializer (SerDes), and twisted pair copper solutions. The current flagship in this last group is the BCM84844 Quad-Port 10GBASE-T Transceiver. Like the X540, this chip is made on a 40 nm process and consumes dramatically less power than its predecessor, although it still must be paired with an XFI or SGMII MAC interface.
