The FMC DIO 5CH TTL A has been designed for testing of the White Rabbit functionality as part of the SPEC Demonstration Package for White Rabbit, and it can be used for other general-purpose applications.

Technical Parameters

Specifications

  • 5 input/output ports with independently programmable direction (Lemo 00 connectors).
  • Output levels: LVTTL, capable of driving +2.5 V over a 50-Ohm load. At power-up the outputs are in Hi-Z state.
  • Input levels: any logic standard from Vih = 1 V to Vih = 5 V (threshold programmable for each input independently).
  • Output rise/fall times: max. 2 ns.
  • I/O bandwidth: 200 MHz.
  • Programmable 50-Ohm input termination in each channel.
  • LVDS I/O on the carrier side.
  • One of the inputs is capable of driving a global clock net in the carrier’s FPGA.
  • Inputs and outputs protected against +15V pulses with a pulse width of up to 10µs at 50Hz.
  • 4-layer PCB

Applications

This module has been designed to be used together with the Simple PCIe FMC Carrier – SPEC, forming a simple White Rabbit node for building ultra-precise time and event distribution networks.
