Communications Designs

This is a sample of some of our communications designs.

4 lane, Gen2 PCI Express Card Design

4-Lane Gen2 PCI Express Card 
This client needed a four lane, Gen2 PCI Express card for a security application. Designed for a Xilinx 7-Series device, it achieved a measured 1.25 GBytes/sec of bandwidth using a custom chain linked list DMA engine. The board included 8 ADCs with LVDS interfaces.  

The Real Time Data Interface 
The RDI is a custom PCI card used for real time distributed motion control systems. This PCI card provides four 500 Mbit/sec links over CAT cable for reliable packet communications, eight linked-list DMA engines which allow real-time scheduled transfers, and nanosecond-class box-to-box synchronization for distributed real-time control operations. The packet protocol breaks transfers into small packets to have a deterministic real-time latency.  Transfers can be either reliable (acknowledged and retried in hardware) or UDP-style with a sequence number provided at the destination.

Remote I/O FPGA and Card Design

Remote I/O Cards 
Verien has designed a number of remote I/O cards for different clients and applications.  These cards take in slower I/O, encapsulate the I/O into packet data, and send it across an optical link a gigabits / second to the second card where the I/O is replicated.  For these, Verien generated the proprietary packet protocol to suit the customers needs.
