Overview
Overview
The V2495 is the completely new version of the CAEN bestseller VME General Purpose Programmable Unit V1495. This new design brings a simpler connectivity, a 150% increase in the logic resources, more programmable Gate&Delay generators and it does all this remaining compatible with previous I/O expansion boards. The board is a suitable solution for the implementation of digital functions such as Coincidence, Trigger Logic, Gate and Delay generator, Input/Output Register and more.

The architecture of the V2495 is based on the User FPGA (Altera Cyclone V 5CGXC4, 50K Logic Elements) which is directly interfaced to the front panel I/Os (up to 162 inputs and up to 130 outputs) and to an internal local bus.
The V2495 can be controlled and programmed "on the fly" via the VME Bus or directly through the USB connector on the front panel. A Software tool is provided for free to easily upload the custom Firmware on the User FPGA.

The V2495 is also completed by 32 internal delay lines that can be used to generate programmable gate and delay signals. The channel interface can be freely expanded by adding up to three independent piggyback boards (there are 3 expansion slots interfaced to the User FPGA), choosing between the five available types:
arrow A395A 32 LVDS/ECL/PECL input channels
arrow A395B 32 LVDS output channels
arrow A395C 32 ECL output channels
arrow A395D 8 NIM/TTL input/output channels
arrow A395E 8 Analog output 16bit channels

Therefore, the V2495 can achieve a maximum number of 194 I/O channels.
Firmware V2495
Firmware
A set of free Firmware demos, complete of full source codes, is available to help the user Firmware development. In addition, the unit can be used as a 160 Channels Multievent Latching Scaler thanks to FW2495SC CAEN Firmware.
Multievent latching Scaler Firmware
Multievent latching Scaler Firmware
FW1495SC and FW2495SC are FPGA firmwares for CAEN x495 models that allows to use the boards as a Multievent latching scaler, suitables for various digital Gate/Trigger/Translator/Buffer/Test applications:
pnt Up to 160 Channel Latching Scaler
pnt 32 or 64-bit channel depth
pnt Multichannel scaler operation with programmable dwell time from 1 μs to 4000 s
pnt 4 k x 32 bits multievent buffer memory
Desktop Version DT5495
Desktop Version
DT5495 is the new programmable logic unit in a desktop form factor, compact and easy to setup. DT5495 is provided of Ethernet and Mini-USB connection, allowing the user to make the most of the operations directly on the front panel.
