The AV107 is part of ApisSys’ range of High Speed data conversion and signal processing solutions based on the VITA 46, VPX standard.

The AV107 is fully compliant with OpenVPX standard, accommodating various communication protocols such as PCIe, SRIO, 1 Gbit and XAUI 10 Gbit Ethernet, as well as non OpenVPX adopted standard such as Aurora.

The AV107 combines four 12-bit 2.5 Gsps ADCs with ultra high processing power delivered by Xilinx® Virtex® 7 FPGA, making it ideally suited for fully synchronous multiple channels test and measurement, Electronic Warfare, Ultra Wideband Radar Receivers or LIDAR applications.

The AV107 features an internal ultra low jitter reference and four independent clock synthesizers and can be used with either external clocks or external reference for higher fl exibility.

The AV107 supports an external trigger signal coupled with a 15ps resolution Time to Digital Converter (TDC).

The AV107 includes one Xilinx® Virtex® 7 FPGA VX415T or VX690T for an impressive processing capability of more than 2 TMACs (Multiply Accumulate per second), one high speed 256M32 DDR3 SDRAM memory for data processing and a 1 Gb synchronous FLASH memory for multiplefi rmware storage.

The AV107 provides a USB 2.0 interface and a 10/100 Ethernet interface intended to be used for system monitoring and supervision.

The AV107 comes with complete software drivers for Windows and Linux. An FPGA Development Kit is provided including all necessary cores to build user FPGA application.

12-bit 2.5 Gsps Analog-Digital Converters

The AV107 Analog to Digital conversion is performed by four 12-bit 2.5 Gsps ADCs with independent 120 or 240 MHz Bandwidth DigitalDown Converters.The AV107 provides four front panel SMPM connectors for analog inputs.Single ended input signals are AC coupled with an input bandwidth from 1 MHz to more than 3 GHz with 6 dBm input level.A wideband signal generator is provided for on board, stand-alone calibration.

Clock

The AV107 provides four independent ultralow jitter clock synthesizers locked on a 100 MHz internal reference.The AV107 provides a front panel SMPM connector for external reference, 10 to 100 MHz as well as a VPX P2 reference input.Four SMPM connectors support either external clock inputs for the ADCs or clock output when the internal clock synthesizers are used. External clock from 1 GHz to 2.5 GHz are supported.Dedicated fine clock phase controls on each channel allow for accurate adjustment of phase delay between all channels.

Trigger and Synchronization

The AV107 support a differential pair on VPX P2 connector used a trigger signal. An embedded Time do Digital Converter with a 15ps resolution allow for fi ne synchronisation on external event.

FPGA

The AV107 is fi tted with a Xilinx Virtex 7 VX415T or VX690T user programmable FPGA. Only few resources are used to control and communicate with external hardware such as DDR3 SDRAM and monitoring subsystem, leaving most of the logic and block RAM and all DSP resources available for customer processing.Dedicated to signal processing, the Xilinx Virtex 7 VX415T FPGA includes 412,160 logics cells, 880 bloc RAM (36 Kbit each), 2,160DSP48E1 slices and 2 PCIe interface blocs.The most powerful version embeds a Xilinx Virtex 7 VX690T which provides 693,120 logics cells, 1,470 bloc RAM and 3,600 DSP48E1 slices for an impressive processing power of more than 2 TMACs.The FPGA is delivered in -2 speed grade.

Memories

The AV107 includes one 667 MHz 256M32 DDR3 SDRAM memory banks and one 1 Gbit synchronous BPI FLASH used to store multipleFPGA confi guration files.

VPX interface

The AV107 features an OpenVPX VITA 65 compliant interface with support for two Fat Pipes for Data Plane, one Fat Pipe for Expansion Plane, two Ultra Thin Pipes for Control Plane and two User Defi ned Ultra Thin Pipes on P1. The AV107 also supports a USB2.0, a 10/ 100 Ethernet and 24 LVDS differential pairs on P2.The AV107 features two low phase noise clock generators able to synthesize clock references for the FPGA GTXs from 100 MHz to 312.5 MHz, allowing support of all major protocols such as Aurora, GigE, PCIe Gen 1 and Gen 2, SATA, SRIO and XAUI 10Gbit Ethernet up to 12.5 Gbps.

Microcontroller

The AV107 features a 32-bit 80 MHz microcontroller used primarily for board monitoring and supervision.The microcontroller supports a USB 2.0 and a 10/100 Ethernet interfaces accessible on the VPX P2 user IO pins through an ApisSys AR102 Rear Transition Module or an ANSI/VITA 46.10 compliant custom RTM board.The microcontroller fi rmware includes all necessary features for board monitoring and supervision.

Firmware

The AV107 comes with a fi rmware package which includes VHDL cores allowing for control and communication with all AV107 hardware resources.A base design is provided which demonstrates the use of the AV107 and gives users a starting point for fi rmware development. The AV107 firmware package is supported on the Xilinx VIVADO® 2012.4 design suite and later.

Software

The AV107 is delivered with software drivers for Windows 7 and Linux.

Ruggedization

The AV107 is delivered in air cooled and conduction cooled standard or rugged versions for use in severe environmental conditions.Standard VITA 47 supported ruggedization levels are EAC4, EAC6, ECC3 and ECC4.
