The BCM5464R 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 BCM5464R is optimized for low-power
and small footprint size to enable high port density applications. The
BCM5464R 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 BCM5464R’s 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 BCM5464R 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
BCM5464R has the lowest power in the industry at 750 mW per port. In
addition, the BCM5464R has extremely low EMI emissions, which
reduces the design constraints required to meet EMI radiation
specifications.
The BCM5464R supports the RGMII, SGMII, and SerDes MAC
interfaces. The RGMII, SGMII, and Serial SerDes are reduced pin count
(12, 6, and 4, respectively, versus 25) versions of the GMII. The RGMII
clock timing can be adjusted to eliminate the board trace delays required
by the RGMII specification. These reduced pin count interfaces simplify
design and lower system cost by reducing the number of layers required
to route high density solutions. In addition, these interfaces allow fewer
pins at the MAC/switch, which reduces the MAC/switch cost by
enabling smaller die sizes than would be possible with full GMII.
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 BCM5464R port 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 BCM5464R cannot automatically correct. This includes 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 BCM5464R 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. This is an issue becoming more prevalent with contemporary cable
installations. The BCM5464R can tolerate over 4 kV of CESD.
