TimEX3 (Timing EXtension board version 3)


Description

The TimEX3 is a multipurpose 3U compact PCI board designed to perform simple to medium complex logical functions.
This board is mainly used for the synchronization system of SOLEIL.

The foreseen uses include:

  • 1 TTL input to 4 TTL outputs signal duplication.
  • 1 TTL input to 4 LVPECL outputs signal conversion and duplication.
  • Top-up gating.
  • Trigger monitoring.

These functions are done with a FPGA and by configuring the board during the manufacturing.
The same PCB is used, but different components will be soldered depending on the function needed.


Architecture

The TimEX3 board is based on a Xilinx Spartan-6 FPGA.
It communicates with the compact PCI bus through a PLX PCI9030 interface. This chip is connected to the FPGA with a simple 60MHz, 32 bits microprocessor bus.
The board can be configured either in 1 TTL input / 4 TTL outputs, or 1 TTL input / 4 LVPECL outputs. This is done during the manufacturing by soldering either the TTL buffers or the LVPECL buffers.

The board is powered by the cPCI bus. The power can also be supplied by an auxiliary connector. In this case, the board will function in standalone. This is useful for signal duplication or top-up gating where a cPCI crate is not required.
