The JazzFiber-V5 Serial Front Panel Data Port (FPDP) I/O module, from TEK Microsystems, uses a Xilinx Virtex-5 FPGA to implement the interface protocol, memory buffering, DMA engines, and local bus/fabric interface. The installed FPGA device depends on the number of channels and the serial baud rate, ranging from a two channel 2.5 Gb/s module which uses an LX50T, to a four channel 6.4 Gb/s module which uses an FX100T. The JazzFiber-V5 module provides the fastest available solution for single and multichannel ANSI/VITA 17.1-2003 Serial FPDP interfaces with the hardware, firmware and software features to support the emerging VITA 17.2 standard for Serial FPDP extensions. The JazzFiber-V5 is available now with standard commercial delivery 8-10 weeks ARO.
Software drivers are available for Windows, Linux and VxWorks operating environments with support for a wide range of x86 and PowerPC host platforms with a common API with support for all Serial FPDP operating modes. The integrated firmware and software transparently support single Serial FPDP streams as well as logical streams using x2 and x4 channel bonding defined in VITA 17.2.
The JazzFiber-V5 is designed from the ground up to operate effectively in laboratory, rugged air-cooled, and rugged conduction-cooled environments meeting the needs of R&D and deployed applications.
Front Panel I/O
The JazzFiber-V5 has four LC-style fiber optic transceivers mounted at the front panel of the module. The fiber optic transceivers may be ordered with either single or multi-mode fiber interfaces at either 850 or 1300 nm wavelengths. The baseline module supports baud rates of 2.5 Gb/s, with alternate speeds between 1.062 and 6.4 Gb/s available as options.
Serial FPDP Protocol
The JazzFiber-V5 implements the Serial Front Panel Data Port (FPDP) protocol, an open standard for sensor-to-processor data links defined by ANSI/VITA 17.1-2003. Serial FPDP provides low protocol overhead, support for synchronization primitives in the data stream and high efficiency. Serial FPDP supports baud rates of 1.062, 2.125, and 2.5 Gb/s, with net data rates up to 247 MB/s after data encoding and protocol overhead. Serial FPDP has been deployed in a wide range of sensor I/O applications and is a well established tool for moving large amounts of data between external sensors and signal or data processor systems.

DDR3 Memory Buffers
The JazzFiber-V5 uses the latest memory technology DDR3 to provide maximum memory throughput at 23% less power than DDR2 based memory. With four independent memory banks clocked at 400 MHz each, the buffer memory subsystem provides aggregate throughput of 6.4 GB/s, supporting full rate deep FIFO buffering of the maximum 25.6 Gb/s fiber optic capability. The baseline module has 512 MB of memory, which provides up to 500 ms of buffering at full 17.1 Serial FPDP rates, decoupling the module from local bus memory latencies. The module will support memory capacities of up to 2 GB when higher density memory devices are available in 2009.
