Gigabit Ethernet
The CP307 board includes two 10Base-T/100Base-
TX/1000Base-T Ethernet ports based on two Intel®
82573L Gigabit Ethernet controllers, which are con-
nected to the x1 PCI Express interfaces of the ICH7-R.
The Intel® 82573L Gigabit Ethernet Controller’s archi-
tecture is optimized to deliver high performance with
the lowest power consumption. The controller's archi-
tecture includes independent transmit and receive
queues and a PCI Express interface that maximizes
the use of bursts for efficient bus usage.
The Boot from LAN feature is supported.
The Ethernet connectors are realized as RJ-45 connectors. The interfaces provide automatic
detection and switching between 10Base-T, 100Base-TX and 1000Base-T data transmission
(Auto-Negotiation). Auto-wire switching for crossed cables is also supported (Auto-MDI/X).
RJ-45 Connector J11A/B Pinouts
The J11A/B connector supplies the 10Base-T, 100Base-TX and 1000Base-T interfaces to the
Ethernet controller.
Note ...
The Ethernet transmission can operate effectively using a CAT5 cable with a
maximum length of 100 m.
