The BCM56803 network switch is a high-density 10-Gigabit Ethernet switching chip solution with 12 ports. All 12 ports can flexibly support HiGig2/HiGig+/HiGig/10-GbE/1-GbE. Additionally, the BCM56803 integrates all the SerDes required to interface with applicable copper and fiber physical fabrics.
The integrated SerDes functionality includes 10-Gbps XAUI and 1-Gbps SGMII PHY interfaces. The integrated SerDes complies with the CX-4 standard and PICMG3.1 standard, which ensures interoperability with Ethernet line cards in an Advanced TCA chassis.
