A395

Piggyback boards for Vx495 and DT5495

  • Five Piggy Back Boards for CAEN Programmable logic Unit:
  • Up to 32 Digital Input/Output
  • LVDS/ECL/PECL/NIM/TTL
  • 8 Analog Outputs (16-bit resolution)
  • Up to 300 MHz Bandwidth

 

Overview

The channel interface of V2495 (V1495) and DT5495 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 V2495 and DT5495 can achieve a maximum number of 194 I/O channels.
