A395x
Piggyback boards for Vx495 and DT5495
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 (refer to the DT5495 User Manual for complete technical specifications and additional information):
- 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.
