The AV119 is part of ApisSys’ range of High Speed data conversion and signal processing solutions based on the VITA 46, VPX standard.

The AV119 is fully compliant with the OpenVPX standard, accommodating various communication protocols such as PCIe, SRIO, 1 Gbit and XAUI 10 Gbit Ethernet, as well as non OpenVPX adopted standards such as Aurora.

The AV119 combines two 12-bit 2.5 Gsps ADCs plus 2 RF out built on 16-bit 2.5 Gsps I/Q DAC and RF modulators 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 Transceivers or MIMO applications.

The AV119 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 flexibility.

 

The AV119 supports an external trigger signal coupled with a 15ps resolution Time to Digital Converter (TDC).

The AV119 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 256M64 DDR3 SDRAM memory for data processing and a 1 Gb synchronous FLASH memory for multiple firmware storage.

The AV119 provides a USB 2.0 interface and a 10/100 Ethernet interface intended to be used for system monitoring and supervision.

The AV119 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 AV119 Analog to Digital conversion is performed by two 12-bit 2.5 Gsps ADCs each with independent 120 or 240 MHz Digital Down Converters.
The AV119 provides two front panel SMPM connectors for analog inputs.
Single ended input signals are AC coupled with an input bandwidth from 1 MHz to more than 5.5 GHz with 10 dBm input level.

16-bit 2.5 Gsps Digital-Analog Converters

The AV119 Digital to Analog conversion is performed by a Quad 16-bit 2.5 Gsps DAC with independent Digital Up Converters.
Two I/Q modulators with more than 1 GHz instantaneous bandwidth allow generation of RF signals from 300 MHz up to 4.5 GHz.
The AV119 provides two front panel SMPM connectors for analog RF outputs.
A loopback mode between RF out and ADC input is provided for on board calibration.

Clock

The AV119 provides four independent ultralow jitter clock synthesizers locked on a 100 MHz internal reference.
The AV119 provides a front panel SMPM connector for external reference, 10 to 100 MHz as well as a VPX P2 reference input. A reference output is available on a front panel SMPM connector and on VPX P2.
Three SMPM connectors support either external clock inputs-outputs for the ADCs and the quad DAC. External clocks from 1 GHz to 2.5 GHz are supported.
An SMPM connector supports an external LO for the IQ modulators.
Dedicated fine clock phase controls on each synthesizer allow for accurate adjustment of phase delay between all channels.

FPGA

The AV119 is fitted 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), 2,160 DSP48E1 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 AV119 also supports a USB2.0, a 10/100 Ethernet and 24 LVDS differential pairs on P2.
The AV119 features two low phase noise clock generators able to synthesize clock references for the FPGA GTHs 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 AV119 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 firmware includes all necessary features for board monitoring and supervision.

Firmware

The AV119 comes with a firmware package which includes VHDL cores allowing for control and communication with all AV119 hardware resources.
A base design is provided which demonstrates the use of the AV119 and gives users a starting point for firmware development. The AV119 firmware package is supported on the Xilinx VIVADO® 2014.4 design suite and later.
