DSP-Based PHY Technology
The BCM5241 builds on Broadcoms 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. Broadcoms DSP-based, Broad-Φ™ technology has been proven in the shipment of over one billion Fast Ethernet ports. Due to the significantly greater test coverage for a DSP based PHY, Broadcoms PHYs exhibit superior quality with a failure rate of well under 10 PPM.
