DSP-Based PHY Technology
The BCM524 1 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,
Broad-φTM 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, Broadcom's PHYs exhibit superior quality with a
failure rate of well under 10 PPM.
Network Tolerance
The BCM524 1 includes features that simplify the installation and
maintenance of local area networks. A simple help tool is the
CableCheckerIM, 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.
Another network tolerance feature is the HP Auto-MDIX capability,
which automatically detects and corrects crossed cables. With HP Auto-
MDIX, the installer does not need to know what is on the other end of the
network cable. The BCM5241 automatically switches its transmit and
receive circuitry to accommodate the link partner' s polarity.
Cable-sourced electrostatic discharge (CESD) is a recently discovered
phenomenon that occurs when an electrically charged network cable is
plugged into a networked product. This is an issue becoming more
prevalent with recent cable installations. The BCM5241 has been
designed and tested to withstand over 2KV of CESD, which unlike other
transceivers, prevents the device from being destroyed in a CESD event.
Low Power Fast Ethernet PHY
The BCM524 1 has an extremely low power dissipation of less than 170
mW. It features an integrated voltage regulator, and can be supplied by
either 2.5V or 3.3V power sources. The BCM5241 employs several
intelligent power- down states that conserve power, while allowing
BCM524 1-based products to automatically turn on when needed.
The BCM5241 includes a unique Intelligent Power-Management feature
that powers down the device if energy is not detected on the cable. This
feature is especially useful for portable and power- sensitive applications.
The BCM5241 can be set to peridically wake up at a user defined
interval, allowing the device to initiate keep-alive network traffic. For
lowest power consumption, the BCM5241 can be put in a power-off state
(<170 mW).
