A member of Broadcom’s third generation of Gigabit Ethernet PHYs,
the BCM5482 consists of two complete 10/100/1000BASE-T Gigabit
Ethernet transceivers integrated on a single monolithic CMOS chip. The
BCM5482 is optimized for low power and small footprint size to reduce
design complexity for space-constrained IP phone applications. For 10/
100BASE-TX applications, the single package offers a compelling
advantage over two single devices for Gigabit uplinks.
The BCM5482 DSP-based architecture and advanced power
management techniques combine to achieve robust and low-power
operation over existing Category 5 twisted-pair wiring. The BCM5482
architecture not only meets the requirements of IEEE 802.3,
IEEE 802.3u, and IEEE 802.3ab, but also maintains the industry’s
highest level of margin over IEEE requirements for echo, near-end
crosstalk (NEXT), and far-end crosstalk (FEXT). With the industry's
lowest power at 600 mW per port, the BCM5482 assists in reducing the
power distribution requirements of IP phone systems. In addition, the
BCM5482 has extremely low EMI emissions, which reduces the design
constraints required to meet EMI radiation specifications.
The BCM5482 supports the RGMII, SGMII, and SerDes MAC
interfaces. The RGMII, SGMII, and serial SerDes inteerfaces 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 for signal routing. 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 Ethernet
copper PHY family, joining more than 25 other quad and single
products. The 0.13-µm process is the optimal process that offers the best
performance, lowest cost, and lowest power for Gigabit Ethernet copper
solutions. Broadcom continues to expand its leadership in 0.13-µm
technology with the BCM5482, part of its third generation of 0.13-µm
Gigabit Ethernet copper transceivers.
Each BCM5482 port is fully independent and has individual interface,
control, and status registers, and incorporates a number of advanced
features. This includes identifying physical wiring defects that the
BCM5482 cannot automatically correct for, and 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 BCM5482 also has ESD tolerance that is well above typical industry
standards. This prevents ESD damage not only during manufacturing,
but also 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 BCM5482 can tolerate over 3 kV
of CESD.
