S750 Radiation Tolerant Gigabit Ethernet PMC
The S750 provides a four (4) port Gigabit Ethernet switch in a compact, single width, PMC form-factor.
Based upon a large capacity, space-rated Xilinx FPGA, the S750 provides GbE switch performance in a
radiation-tolerant, space-rated product. The FPGA based S750 provides the unique ability for the
performance to be quickly customized to meet the most demanding Earth orbit or deep space applications.
The feature set provided by the S750 product is as follows:

Designed to operate and host on the Aitech S950 or SP0 Single Board Computer (SBC)

Optimized to switch and transfer data between the SBC and each S750 GbE network port

Switches data between all ports based on the Media Access Control (MAC) Forwarding Table

Stores dynamically learned host MAC addresses of devices connected to the S750 in the MAC
Forwarding Table

Provides real-time status to the SBC software using memory-mapped access over the local PCI bus

Operational switch status and functions of each Ethernet port are presented to the SBC target software
application via the Local PCI bus

Onboard 1500-byte FIFO and DMA data fed directly into a pre-defined 8-MBytes buffer on the S950
triple-voted volatile memory for data traffic. VxWorks END driver provided for the host (primitive) port

Supports transmit and receive Internet Protocol Version 4 (IPv4) RFC 791, User Datagram Protocol
(UDP) RFC 768 (TBR 114) and Transmission Control Protocol (TCP) data packets

Managed via software on the host carrier PMC mother board.



Configurable MAC address function provided for the host (primitive) port

Host configuration remains unchanged across power cycles by storing configuration data in the SBC
user Flash

User application can save S750 configuration in Flash including address table(s)

Provide a PCI interface to configure static entries in the forward lookup Media Access Control table

MAC forwarding table with 64 user accessible dynamic entries and 16 user accessible static entries

MAC translation table with 16 entries

Supports dynamic destination MAC Address modification of a received Ethernet frame according to a
configurable translation table prior to transmission to the destination port

Memory mapped register to enable or disable the operation of each GbE Ethernet port or to enable or
disable the MAC Address Translation function

The Switch 100/1000Base-T ports are compliant to the IEEE-STD-802.3-2005 Clauses 2, 3, 4, 28, 35
and 40 (except for half-duplex support)
