• Manufacturer Part Number: bcm54610
• Description: 10/100/1000base-t Gigabit Copper Transceiver
• Manufacturer: Broadcom Corp.

The BCM54610 is optimized for low power and small footprint size to
enable uplink and general GbE connectivity applications. By lowering
system cost and reducing power dissipation, the BCM54610 enables a
new class of cost-effective GbE equipment, driving the delivery of
Gigabit bandwidth to the desktop.
The BCM54610 digital signal processor-based architecture and
advanced power management techniques combine to achieve robust and
low power operation over the existing CAT-5 twisted-pair wiring. The
BCM54610 architecture also meets the requirements of 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 a key
factor in implementing Gigabit small form factor NICs and uplinks, and,
at less than 500 mW per port, the BCM54610 has the industry's lowest
power. Additionally, the BCM54610 has extremely low EMI emissions,
which reduces the design constraints required to meet EMI emissions
specifications.
The BCM54610 supports the IEEE 802.3 standard Reduced Gigabit
Media Independent Interface (RGMII). RGMII is a reduced pin-count
(12 versus 25) version of the Gigabit Media Independent Interface
(GMII). The small package, multiple MAC interfaces, and streamlined
power supply lower system cost and simplify the system and board level
design.

This device is another member of the Broadcom 65-nm Gigabit copper
PHY family, joining the BCM54680. The optimal 65-nm process offers
the best performance, lowest cost, and lowest power for Gigabit copper
solutions. Further, devices based on the 65-nm 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.
The BCM54610 incorporates a variety of advanced features. The link
quality indicator LED provides installers with immediate visual
notification of any problems with the wiring plant supporting operation
at the desired speed. This includes physical wiring defects that the
BCM54610 cannot automatically correct and channel conditions such as
excessive cable length and return loss, crosstalk, echo, and noise.
Broadcom cable analyzer software can be used with the device to
provide remote management of the cable and first-level diagnostics and
fault isolation.
The BCM54610 also has ESD tolerance that exceeds typical industry
standards. This feature not only prevents ESD damage during
manufacturing but also during cable-sourced electrostatic discharge
(CESD) events in the field. CESD is an ESD event that occurs when an
electrically charged network cable is plugged into a network port, an
issue becoming more prevalent with contemporary cable installations.
