The BCM5464S 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 QuadSquadTM family of quad Gigabit
Ethernet PHYs. The BCM5464S is optim ized fo r low-po wer and sma ll
footprint size to enable high port density applications. The BCM5464S
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 bandwi dth to the desktop.
The BCM5464S 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 BCM5464S 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
BCM5464S has the lowest power in the industry at less than 750 mW per
port. In addition, the BCM5464S has extremely low EMI emissions,
which reduces the design constraints required to meet EMI radiation
specifications.
The BCM5464S supports GMII, RGMII, SGMII, and SerDes MAC
interfaces. A unique feature of the BCM5464S is its ability to support
both copp er and fib er networks, with an integrated SerDes PHY int erface
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 BCM5464S monitors copper link and
fiber signal detect status, and automatically swaps either copper traffic or
fiber traffic to the MAC/switc h base d on priorit ies set at initializ atio n.
This device i s another me mber of Broad com’s 0. 13-µm Gigabi t copper
PHY family, joining the BCM5404, BCM5414, BCM5421, BCM5421S,
BCM5424, and BCM5434. The 0.1 3- µm process i s the optim al 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 par t.
Each port of the BCM5464S 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 BCM5464S cannot automatically correct for,
channel conditions such as excessive cable length and return loss,
cross talk, echo , and noise. Broadcom’ s cable anal yzer softwa re can be
used with the device to provide remote management of the cable and a
first level of diagnostics and fault isolation.
The BCM5464S 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.
