• Manufacturer Part Number: bcm5464sr
• Description: Bcm5464sr - Quad-port 10/100/1000base-t Gb Transceiver With Copper/fiber Media Interface
• Manufacturer: Broadcom Corp.

The BCM5464SR consists of four complete 10/100/1000BASE-T Gigabit
Ethernet transceivers integrated on a single monolithic CMOS chip, and is
a member of Broadcom’s QuadSquad™ family of quad Gigabit Ethernet
PHYs. The BCM5464SR is optimized for low-power and small footprint
size to enable high port density applications. The BCM5464SR enables a
new class of cost effective Gigabit Ethernet equipment by lowering system
cost and reducing power dissipation by nearly 25%, driving the delivery of
Gigabit bandwidth to the desktop.
The BCM5464SR digital signal processor based architecture and advanced
power management techniques combine to achieve robust and low-power
operation over the existing Category 5 twisted-pair wiring. The
BCM5464SR architecture not only meets the requirements of IEEE’s
802.3, 802.3u, and 802.3ab, but maintains the industry’s highest level of
margin over IEEE requirements for echo, NEXT, and FEXT. Low-power
is key to implementing high-density Gigabit switches, and the
BCM5464SR has the lowest power in the industry at less than 750 mW per
port. In addition, the BCM5464SR has extremely low EMI emissions,
which reduces the design constraints required to meet EMI radiation
specifications.
The BCM5464SR supports RGMII, SGMII, and SerDes MAC interfaces.
A unique feature of the BCM5464SR is its ability to support both copper
and fiber networks, with an integrated SerDes PHY interface that can
connect directly to a fiber-optic module. Switching between copper and
fiber media can be accomplished either automatically or through software
control. The BCM5464SR monitors copper link and fiber signal detect

status, and automatically swaps either copper traffic or fiber traffic to the
MAC/switch based on priorities set at initialization.
This device is another member of Broadcom’s 0.13-µm Gigabit copper
PHY family, joining the BCM5404, BCM5414, BCM5421, BCM5421S,
BCM5424, and BCM5434. The 0.13-µm process is the optimal process that
offers the best performance, lowest cost, and lowest power for Gigabit
copper solutions. Devices based on the 0.13-µm process offer an excellent
long term cost curve, enabling better cost reduction over time compared to
older technologies without having to redesign or requalify a new part.
Each port of the BCM5464SR is fully independent and has individual
interface, control and status registers, and incorporates a number of
advanced features. A link quality indicator LED gives installers an instant
visual indication if there are any problems with the wiring plant supporting
operation at the preferred speed. This includes physical wiring defects that
the BCM5464SR cannot automatically correct for, channel conditions such
as excessive cable length and return loss, crosstalk, echo, and noise.
Broadcom’s cable analyzer software can be used with the device to provide
remote management of the cable and a first level of diagnostics and fault
isolation.
The BCM5464SR also has ESD tolerance well above typical industry
standards. This prevents ESD damage not only during manufacturing but
during CESD events in the field. The CESD is an ESD event that occurs
when an electrically charged network cable is plugged into a network port,
which is an issue becoming more prevalent with recent cable installations.
The BCM5464 can tolerate over 4 kV of CESD.
