DT5495

Overview

The CAEN Mod.DT5495 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 boards are 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 DT5495 is based on the User FPGA (Altera Cyclone V GX C4, 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 DT5495 can be controlled and programmed via Ethernet or Mini-USB on the front panel. A Software tool is provided for free to easily upload the custom Firmware on the User FPGA.

The DT5495 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:

• A395A: 32 LVDS/ECL/PECL input channels
• A395B: 32 LVDS output channels
• A395C: 32 ECL output channels
• A395D: 8 NIM/TTL input/output channels
• A395E: 8 Analog output 16 bit channels

Therefore, the Mod. DT5495 can achieve a maximum number of 194 I/O channels.

FW2495SC is a FPGA firmware that allows to use the DT5495 as a Multievent latching scaler housing up to 160 independent counting channels (this maximum number of channels is achieved if the DT5495 is expanded with three A395A boards).
