18 Functional Description
3.4 Peripherals
The following peripherals are available on the AMC-1000 board:
3.4.1 Gigabit Ethernet Interfaces
The AMC-1000 module is designed with an Intel® 82571EB Dual
Gigabit Ethernet Controller, using the Intel® 3100's PCI Express
x4 interface to offer two 1000BASE-BX Ethernet ports for AMC.2
support.
The Intel® 82571EB Dual Gigabit Ethernet Controller’s architec-
ture is optimized to deliver high performance with the lowest
power consumption. The controller’s architecture includes inde-
pendent transmit and receive queues and a PCI Express interface
that maximizes the use of bursts for efficient bus usage.
3.4.2 USB Interfaces
The AMC-1000 supports four USB 2.0 ports:
X one mini-B type USB port on front panel
X two ports are routed to rear
X one channel for 4GB on-board NAND flash
The USB 2.0 ports are high-speed, full-speed, and low-speed
capable. Hi-speed USB 2.0 allows data transfers of up to 480 Mb/s
- 40 times faster than a full-speed USB (USB 1.1). One USB
peripheral may be connected to each port.
To connect more USB devices than there are available ports, an
external hub is required.
On the USB 2.0 front panel port, USB cable with up to 5 meters in
length can be used. On the USB 2.0 Rear I/O ports, it is strongly
recommended to use a cable below 3 meters in length for USB 2.0
devices.
NOTE:
NOTE:
The AMC-1000 host interfaces can be used with maximum
500 mA continuous load current as specified in the Universal
Serial Bus Specification, Revision 2.0. Short-circuit protection
is provided. All the signal lines are EMI-filtered.
