AV122

14-bit 3 Gsps Analog-Digital Converters

The AV122 Analog to Digital conversion is performed by four AD9208 dual channel 14-bit 3 Gsps ADCs with independent Digital Down Converters with decimation factor ranging from 2 to 48 in complex mode.The AV122 provides eight front panel SMPM connectors for analog inputs.Single ended input signal are AC coupled with an input bandwidth from 1 MHz to more than 9 GHz with 7 dBm input level.

Clock

The AV122 provides one ultra-low jitter clock synthesizer locked on a 100 MHz internal reference.The AV122 supports a 10 to 800 MHz external reference input either from a front panel SMPM connector or from the VPX P2 Connector.A reference output is available on VPX P2.External clock inputs for the ADCs are supported from either one SMPM connector or VPX P2. External clock from 2.5 GHz to 6 GHz are supported (6.0 GHz in divide by 2 mode).External clock outputs are provided on an SMPM connector and on VPX P2.

Trigger and Synchronization

The AV122 supports a differential pair on VPX P2 connector to be used as trigger or synchronization signal.

FPGA

The AV122 is fitted with a Xilinx® Kintex® Ultrascale™ KU115 user programmable FPGA. Only few resources are used to control and communicate with external hardware such as DDR3 SDRAM and monitoring sub-system, leaving most of the logic and block RAM and all DSP resources available for customer processing.Dedicated to signal processing, the Xilinx Kintex Ultrascale KU115 FPGA includes 1,451 K logics cells, 2,160 36 Kbit RAM blocs, 6 PCIe interface blocs and 5,520 DSP48 slices for an impressive processing power of more than 7 TMACs.The FPGA is delivered in -2 speed grade.

Memories

The AV122 includes two 800 MHz 256M64 DDR3 SDRAM memory banks and two 1 Gbit QSPI FLASH used to store multiple FPGA configuration files.

VPX interface

The AV122 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 AV122 also supports 26 LVCMOS33 signals and 4 SUB-LVDS differential pairs on P2 plus USB2.0 and 10/100 Ethernet for supervision and monitoring.The AV122 features two low phase noise clock generators able to synthesize clock references for the FPGA GTHs from 60 MHz to 820 MHz, allowing support of all major protocols such as Aurora, GigE, PCIe Gen 1, 2 and 3, SATA, SRIO and XAUI 10Gbit Ethernet up to 16.375 Gbps.

Microcontroller

The AV122 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 AV122 comes with a firmware package which includes VHDL cores allowing for control and communication with all AV122 hardware resources.A base design is provided which demonstrates the use of the AV122 and gives users a starting point for firmware development. The AV122 firmware package is supported on the Xilinx VIVADO® 2017.4 design suite and later.

Software

The AV122 is delivered with software drivers for Windows 10 and Linux.

Ruggedization

The AV122 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.
