Frame Synchronous Buffer (FSB), Model TCP-FSB-01
Pricing: $6,000 for a single device; quantity discounts are available.

The Frame Synchronous Buffer is a dual-channel serial communications controller that receives and transmits high rate, synchronous, proprietary frame-formatted data streams, buffering the data for a connected host system while internal and external I/O operations occur. The FSB connects to a host notebook, desktop, or rack-mount system via a USB 2.0 port that acts as both a data path and power source. The FSB uses a Cypress FX2 USB Slave microcontroller as its control processor and host interface, a Xilinx Spartan-3 FPGA to execute its proprietary communications protocols, and Linear Technologies line drivers to enable communications over RS-530 and RS-232 circuits. Data rates up to 10 Mbits/sec are possible depending on the protocol employed. Device driver and evaluation software are available for use with the Red Hat Enterprise Linux 5.x OS on PC and Power PC platforms, and with the Linux Fedora 8 OS on PC platforms. Customization of device driver and supporting applications software are available for an additional fee.
