BCM5722
I
NTRODUCTION
The BCM5722 NetXtreme and NetLink family of Media Access Controller (MAC) devices are highly-integrated, single-chip
gigabit Ethernet LAN controller solutions for high-performance network applications. The above devices integrate the
following major functions to provide a single-chip solution for gigabit LAN-on-motherboard (LOM) and network interface card
(NIC) applications. BCM5906 and BCM5906M are 10/100-Mbps devices only.
• Triple-speed IEEE 802.3-compliant MAC functionality
• Triple-speed IEEE 802.3-compliant Ethernet PHY transceiver
®
• PCI Express (PCIe™) bus interface
• On-chip packet buffer memory
• On-chip RISC processor for custom frame processing (not applicable to BCM5906)
• SMBus interface for Alert Standard Format (ASF) version 2.0 support (not applicable to BCM5906)
• The BCM5755 and BCM5755M MACs also support the integrated Trusted Platform Module (TPM) security engine
compliant with the Trusted Computing Group™ main specification version 1.2, and low pin-count interface support.
