Block Diagram
The BCM5704C is a fully integrated dual-port, 10/100/1000BASE-T
Gigabit Ethernet (GbE) MAC and physical layer transceiver solution for
high-performance network applications. The BCM5704C is a highly
integrated solution combining two triple-speed, IEEE 802.3-compliant
MACs, PCI, and PCI-X bus interfaces, an on-chip buffer memory, and
an integrated physical layer transceiver in a single device. The
BCM5704C is fabricated in a low-voltage, 0.13 µm CMOS process
providing a low-power system solution. By itself, the BCM5704C
provides a complete single-chip dual-port GbE NIC or LOM solution.
The BCM5704C includes two 10/100/1000-Mbps Ethernet MACs with
full-/half-duplex capability at all speeds and two 10/100/1000 copper
PHYs. Support for the following IEEE 802.3™ functions is featured in
the MAC: VLAN tagging, Layer 2 priority encoding, link aggregation,
and full-duplex flow control.
visual indication if there are any issues with the wiring plant supporting
operation at the desired speed. This includes physical wiring defects or
channel conditions, such as excessive cable length, return loss, crosstalk,
echo, and noise. Broadcom’s remote cable management and diagnostics
software can be used with the device to provide remote management of
the cable and a first level of diagnostics and fault isolation. The
BCM5704C continually monitors various channel conditions. The
optional wirespeed capability allows the BCM5704C to force auto-
negotiation to be automatically limited by the speed that the channel can
reliably support, rather than the performance of the end equipment.
Target applications of the BCM5704C:
Network Interface Card (NIC) Designs
Dual Port
LAN on Motherboard (LOM) Designs
Dual Port
Although the device provides a single PCI v2.2/PCI-X v1.0 bus
interface, the device functions as if there are two logical software
interfaces. Interrupts are handled via two interrupt pins (INTA and
INTB) on the PCI connector. Individual MAC on-chip memory provides
packet buffering for higher performance and load balancing. Each MAC
function contains dual (TX and RX) on-chip processors enabling custom
frame processing features, including TCP segmentation.
The transceiver is fully compatible with the IEEE 802.3 standard for
auto-negotiation of speed. Additionally, several Plug and Play
enhancements have been added to make the device even more
user-friendly. A link quality indicator LED gives installers an instant
