Description

The BCM5241 builds on Broadcom's proven DSP PHY design and full custom circuit design techniques to create a highly integrated and robust physical layer solution. DSP techniques allow the BCM5241 to achieve high interoperability and to exhibit robust performance across voltage (+/-10%), temperature, and process variations. Broadcom's DSP-based, Digi-PHY™BCM5241  technology has been proven in the shipment of over 500,000,000 Fast Ethernet ports. Due to the significantly greater test coverage for a DSP based PHY, Broadcom's PHYs exhibit superior quality with a failure rate of well under 10 PPM.

The BCM5241 includes features that simplify the installation and maintenance of local area networks. A simple help tool is the Cable Auto-check, which enables basic cable issues to be resolved without contacting technical support. These issues include not plugging the cable correctly at one or both ends, identifying if the cable is damaged, or determining if the remote system is powered up.
