2.3.4
Serial Ports
The AM4100 provides two serial ports, SER0 and SER1, both fully compatible with the 16550
UART.
The SER0 interface provides receive and transmit signals as well as additional signals for
handshaking mode. SER0 is available on the front panel as a serial RS232, 8-pin, RJ45, con-
nector J4. Data transfer rates up to 115.2 kB/s are supported.
The SER1 interface provides only receive and transmit signals. SER1 is available on the AMC
port 15 in the Extended Options Region of the AMC Card-edge connector as TTL 3.3 V signal
level. Data transfer rates up to 115.2 kB/s are supported.
The following figure and table provide pinout information for the serial port connector J4.
2.3.5
Gigabit Ethernet Interfaces
The MPC8641D processor integrates four enhanced three-speed Ethernet controllers (eTSECs)
complemented with an external BCM5466R QUAD Ethernet PHY. The PHY device supports
10BASE-T/100BASE-TX/1000BASE-T as well as 1000BASE-BX (SerDes) interfaces.
The Ethernet channels 1 and 3 of the MPC8641D are assigned to the AMC Base Interface as
SerDes ports. Channels 2 and 4 can be directed to the front panel RJ45 connector. In certain
board versions, these channels are configured as SerDes ports and directed to the AMC ports
8-9 in the Extended Options Region of the AMC Card-edge connector.
Two Gigabit Ethernet configurations are available on the AM4100:
•
Configuration with two Gigabit Ethernet TX interfaces on the front panel and
two Gigabit Ethernet SerDes interfaces on the AMC Card-edge connector
In this configuration two Gigabit Ethernet copper ports (1000BASE-TX) are connected to
the RJ45 front panel connector and two Gigabit Ethernet SerDes ports are routed to the
AMC ports 0-1 in the Common Options Region of the AMC Card-edge connector.
•
Configuration with four Gigabit Ethernet interfaces
In this configuration two Gigabit Ethernet SerDes ports are routed to the AMC ports 0-1
in the Common Options Region of the AMC Card-edge connector and two additional
Gigabit Ethernet SerDes ports are routed to the AMC ports 8-9 in the Fat Pipes Region
of the AMC Card-edge connector.
