Leverage Technology for Broadband Communications Applications
We initially expanded our mixed-signal and digital signal processing technology expertise beyond storage applications for computers and communications equipment through the introduction of physical layer devices using the Fast Ethernet networking protocol. These physical layer devices provide long distance signal transmission capability and low power consumption. We then applied our technology to developing Gigabit Ethernet and 10 Gigabit Ethernet physical layer devices. Additionally, we have integrated our physical layer devices with functions previously provided by other integrated circuits, such as
the MAC. The MAC is the component that controls access by different devices to the physical media to ensure that signals sent from different devices over the same channel do not collide.
We have combined our physical layer transmission solutions with our high-performance switching and internetworking products. By utilizing our system architecture expertise we have integrated multiple product functions to address the demands of today's communications equipment. Our complete product offering is targeted at the business enterprise market where networks are being converged to handle voice, video and data across LANs and WANs.
