Overview

1. Overview

Figure  1:

 Block circuit diagram

The CPCI-CAN/400-2 is a CompactPCI

®

 board in 3U format, that features two electrically isolated

high-speed CAN interfaces according to ISO 11898-2. CAN is driven by the esd Advanced CAN
Core (esdACC) CAN controller implemented in the Xilinx

®

 Spartan

®

 3e FPGA. 

The CPCI-CAN/400-2 provides high resolution hardware timestamps.

The CPCI-CAN/400-2 optionally features a PXI interface.
The signals TRG 0-7, CLK 10 and STAR are controlled via the FPGA. The signals LBL/LBR1-12
are looped through. 
The PXI interface is available on request.
