The AV101 is part of ApisSys' range of High Speed data conversion and signal processing solutions based on the VITA 46, VPX standard.

The AV101 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 AV101 combines the highest performances 10-bit 10 Gsps ADC with ultra high processing power delivered by Xilinx® Virtex® 6 FPGA, making it ideally suited for test and measurement, Electronic Warfare, Ultra Wideband Radar Receivers or LIDAR applications.

The AV101 features an internal ultra low jitter reference and clock generation and can be used with either external clock or external reference for higher flexibility.

 

The AV101 supports an external trigger signal used to synchronize processing with external events.

The AV101 includes one Xilinx® Virtex® 6 FPGA LX195T/LX240T/SX315T or SX475T for an impressive processing capability of up to 1 TMACs (Multiply Accumulate per second), one high speed 2M36 QDRII+ SRAM memory for data processing and one FLASH memory for multiple firmware storage.

The AV101 provides a USB 2.0 interface and a 10/100 Ethernet interface intended to be used for system monitoring and in stand alone mode.

The AV101 comes with complete software drivers for Windows and Linux. An FPGA Development Kit is provided including all necessary cores to build user FPGA application.

     

10-bit 10 Gsps Analog-Digital Converter

The AV101 Analog to Digital conversion is performed by a 10-bit 10 Gsps ADC using multiple ADCs interleaving technologies.
The AV101 provides one front panel MMCX connector for analog input.
Single ended input signal is AC or DC coupled (assembly option) with an input bandwidth from DC to more than 3 GHz with 2 dBm input level.
A wideband signal generator is provided for on board, stand-alone calibration.

Clock

The AV101 provides an internal ultra low jitter clock generator locked on a 100 MHz internal reference.
The AV101 provides a front panel MMCX connector for external reference, 10 to 100 MHz, a front panel MMCX connector for an external clock input, from 1.8 GHz to 2.5 GHz (1/4 of sampling rate) and a front panel MMCX for an external clock output.
A dedicated fine clock phase control allows for accurate adjustment of phase delay between interleaved ADCs.

Trigger and Synchronization

The AV101 provides a front panel MMCX connector for external trigger input coupled with a 15 ps resolution TDC.

FPGA

The AV101 is fitted with a Xilinx Virtex 6 LX195T/LX240T/SX315T or SX475T user programmable FPGA. Only few resources are used to control and communicate with external hardware such as QDRII+ SRAM and monitoring sub-system, leaving most of the logic, block RAM and DSP resources available for customer processing.
Dedicated to signal processing, the Xilinx Virtex 6 LX195T FPGA includes 199,680 logics cells, 344 bloc RAM (36 Kbit each), 640 DSP48E1 slices, 2 PCIe interface blocs and 4 10/100/1000 Ethernet MAC blocs. The most powerful version embeds a Xilinx Virtex 6 SX475T which provides 476,160 logics cells, 1,064 bloc RAM and 2,016 DSP48E1 slices for an impressive processing power of up to 1 TMACs.
The FPGA is delivered in -2 speed grade.

QDRII+ SRAM Memory

The AV101 includes one 2M36 QDRII+ SRAM memory clocked at 350 MHz for a peak data rate of 6.3 GB par second.

 

FLASH Memory

The AV101 includes one 1 Gbit BPI FLASH used to store multiple FPGA configuration files.

VPX interface

The AV101 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 Defined Ultra Thin Pipes on P1.
The AV101 also supports a USB2.0, a 10/100 Ethernet and 28 LVDS differential pairs on P2.

Firmware

The AV101 comes with a firmware package which includes VHDL cores allowing for control and communication with all AV101 hardware resources.
A base design is provided which demonstrates the use of the AV101 and gives users a starting point for firmware development.
The AV101 firmware package is supported on the Xilinx ISE® 13 design suite and later versions.

Software

The AV101 is delivered with software drivers for Windows 7 and Linux.
An application example is provided.

Ruggedization

The AV101 is delivered in air cooled and conduction cooled standard or rugged versions for use in severe environmental conditions.
