S740

Description:

The S740 Communications PMC Module is a single width, conduction-cooled PCI mezzanine card (PMC) designed and characterized primarily for space applications. The board features 16 RS-422 differential inputs and 16 RS-422 differential outputs with onboard FPGA logic to interface to the external spacecraft sensors and devices.

S740 has an onboard PCI Bus DMA controller to move data to/from system buffers and the local onboard SDRAM buffers. An additional DMA controller moves data to/from the SDRAM buffers to/from the serial I/O ports. Output data packets are automatically sent out from the on board buffers and incoming data packets are stored on board until a programmable packet size is received and the local DMA controller then transfers received data to global memory across the PCI bus.

The module is available in several ruggedization levels.

Key Features:

• 16 Input and 16 Output Differential channels of RS-422, LVDS, MLVDS
• Optional up to 64 TTL Drivers and/or Receivers (or mixture I/O standards)
• Custom and Standard Product FPGA Control Logic available for a variety of spacecraft standard or custom data interfaces
• Serial I/O can be configured to NRZ-L, NRZ-M and BiPhase-L Modes with changes to the FPGA
• DMA engine for data transfer to and from the SBC via the local PCI (PMC) Bus
• 128 Mbytes of ECC Protected On-Board Memory Integrated with DMA controller for Input and Output data packet buffering
• Rear I/O via the Motherboard (SBC or Carrier Card) to the cPCI backplane
• Software Configurable Interrupt capability to indicate completion of DMA controlled packet data transfers
• IEEE 1101.2 (conduction cooled) for both engineering unit and flight unit
• 32-bit PCI 3.0 compliant PCI Master/Slave interface at 33.333 MHz
• nominal power consumption is less than 5 Watts
