BCM5723 Broadcom Corp., BCM5723 Datasheet - Page 2

• Manufacturer Part Number: BCM5723
• Description: Integrated Gigabit Ethernet Controller
• Manufacturer: Broadcom Corp.

The BCM5723 is an eleventh-generation 10/100/1000-Mbit BASE-T
Ethernet LAN controller solution for high-performance network
applications. The device combines a triple-speed IEEE 802.3-compliant
media access controller (MAC) with a triple-speed Ethernet transceiver,
x1 PCIe bus interface, and on-chip buffer memory in a single device. The
BCM5723 is fabricated in a 1.2V CMOS process, providing a low-power
system solution.
The BCM5723 includes a 10/100/1000-Mbps Ethernet MAC with full-
duplex and half-duplex capabilities at all speeds. Support for the
following IEEE 802.3™ functions is featured in the MAC:
• VLAN tagging
• Layer 2 priority encoding
• Full-duplex flow control
The device performs all the physical layer functions for 1000BASE-T,
100BASE-T, and 10BASE-T Ethernet on standard Category 5 UTP
cable. Based on proven DSP technology, the device is a highly integrated
solution combining digital adaptive equalizers, ADCs, PLLs, line
