The QuiXilica Triton-V6 VXS is a 6U ANSI / VITA 41 (VXS) compliant high-speed digitizer board combines high density FPGA processing with one 10-bit A/D input channel performing at 2.2 GSPS (Gigasamples per second) and one 12-bit DAC output channel performing at up to 4.0 GSPS.

1 x 2.2 GSPS x 10-bit ADC
1 x 4.0 GSPS x 12-bit DAC
By employing three Xilinx Virtex-6 FPGAs, Tekmicro’s Triton-V6 ombines high resolution wideband signal acquisition and generation with the onboard high density FPGA processing for a range of radar and Electronic Warfare applications such as target generation, jamming, and CM / CCM techniques. The result is a single slot solution that utilizes the latest ADC and DAC technology, supports advanced signal processing of up to 2.75 GB/s of digitized data, and forwards the results through VME, VXS or front panel connection via SFP+ or CXP to the next processing stage.
Triton-V6 transfers full sensor-rate data from the ADC processing (signal capture) to the DAC processing (waveform generation). This is an ideal solution for electronic warfare applications such as jammers and radar decoys.
Triton-V6 features high bandwidth, low latency interconnect paths between its FPGAs. These have been carefully specified to ensure that data from the ADC input can be routed to the DAC output in support of low latency applications. Synchronization of ADC and DAC sampling on a single board, and on multiple boards, is done using an external trigger signal. This offers significant throughput advantages for a range of advanced processing algorithms including coherent multi-channel algorithms found in applications such as direction finding, Space Time Adaptive Processing (STAP) radar, EW, ELINT and Synthetic Aperture Radar (SAR) image formation.
The Triton-V6 is available for a wide range of operating environments including commercial grade, rugged air cooled, and conduction cooled to support deployed applications such as unmanned airborne, naval and ground vehicles. For more details, see Tekmicro’s Ruggedization Data Sheet.
In addition to Triton-V6, Tekmicro offers a broad range of Xilinx Virtex-6 based streaming I/O and FPGA processing solutions for both analog and digital I/O in a range of form factors.

One channel of 2.2 GSPS, 10-bit resolution digital to analog conversion is provided on the Triton-V6 via the e2v AT84AS008. The input is AC coupled with a full scale input level of -2 dBm (0.5V p-p) into 50 Ω. The input may be single-ended or differential (factory build option).
One channel of up to 4.0 GSPS, 12-bit resolution digital to analog conversion is provided using the non-interpolating Euvis MD653D which has a bandwidth of 4 GHz.
The output is AC coupled and may be single-ended or differential (factory build option). Full scale output is -4 dBm (0.4V p-p) into 50 Ω. The DAC can be operated in normal-hold mode, or for extended operation into the 2nd Nyquist band, in Return to Zero (RZ) mode.
Xilinx Virtex-6 FPGAs are the heart of the Triton-V6. The FPGAs interface between the ADC’s, DAC, memory and I/O resources to provide a platform for implementing high performance real time processing. Triton-V6 is configured with three high pin count Xilinx Virtex-6 devices (LX240, SX315, or SX475) per board. Other device types can be used optionally or mixed for custom configurations. All FPGAs are interconnected by wide parallel LVDS busses and via high speed Aurora serial links using the Xilinx GTX transceivers.
Front Panel High Speed Serial I/O
One 12-fiber CXP site is provided on the front panel for standard protocols such as Gigabit Ethernet or Serial FPDP (ANSI VITA 17.1 & 17.2). CXP modules and breakout cables are available optionally for flexible I/O capability.
Onboard Gigabit Ethernet Networking and Switching
An onboard Gigabit Ethernet Switch connected to each FPGA supports routing of control plane signaling and minimizes FPGA involvement for data distribution/forwarding between FPGAs. A dedicated SFP port which supports both fiber and copper 1000 baseT ethernet connections is available to connect to an outside network.
VXS Backplane High Speed Serial I/O
The Triton-V6 can be used as a VITA 41.0 payload card. Up to eight high speed serial links of up to 3.125 Gb/s full duplex data rates are supported via VITA 41.0 MultiGig RT2 P0 connector. Custom or standard communication protocols can be run over these links by providing appropriate firmware in the FPGA.
QuiXstart FPGA Configuration
A number of options are available for configuring the FPGA on the Triton-V6. A JTAG connection is available to allow users to configure the FPGA via standard Xilinx development tools. Onboard flash is available and can configure the FPGA on power up. Tekmicro’s QuiXstart tool supports flexible configuration of the FPGA through a Gigabit Ethernet link from a remote server after a power up or reset event.
Trigger input connections are provided on the front panel to allow the hardware to be employed in a variety of radar and electronic scenarios. The trigger inputs are LVDS (LVPECL is a factory build option). One trigger input serves the DAC channels, and a second serves the ADC channels, or a single trigger input can used for all eight analog IO channels. The trigger inputs may be used to synchronize multiple Triton-V6 boards to within a single sample period.
One clock input serves the four ADC channels, and a second clock input serves the four DAC channels, or all eight analog I/O channels may be clocked from a single clock input (factory build option).
Triton-V6 has two independent banks of onboard DDR3 SDRAM for each FPGA. The front end FPGAs have two 1 GB banks, each with throughput of 6.4 GB/s, while the back end FPGA has two 512 MB banks, each with throughput of 3.2 GB/s. The total memory capacity is 5 GB with aggregate throughput of 32 GB/s across six banks. All DDR3 memory banks are clocked at 400 MHz for an 800 MT/s transfer rate. In addition, there are two fully independent banks of QDRII+ SRAM memory for the back end FPGA. Each QDRII+ device has a 72 Mbit capacity (144 Mbit total) supported by an 18-bit data bus per bank.
For general purpose I/O signals, the Triton-V6 can be accessed via the P2 connector and there is also an SSMC connector on the front panel which can be used for such things as a GPS signal, etc.
System Monitoring / Damage Protection
The Triton-V6 includes facilities to monitor current and temperature at various points on the board. Current monitoring of all main power rails is available through the use of a Spartan-6 FPGA. Die temperature monitoring of the three FPGAs and temperature monitoring of three locations on the PCB is also available. This allows a first level of protection when the Triton-V6 is operating in different environmental scenarios. The output from the sensors is available to the user’s FPGA firmware applications, to allow the application to adapt to changes in environmental conditions. The Triton-V6 also uses the system monitoring sensors to implement a system protection mechanism which will, independently of the user’s application, prevent excessive current or temperature from damaging the board.
