FMC DIO 32ch TTL a
Project description
Sample text - to be replaced>*
The fmc-dio-5chttla 5-channel digital I/O module is a simple board for
digital I/O on LEMO connectors.
It has been designed for testing White Rabbit functionality as part of
the SPEC Demonstration Package for White Rabbit (manual), and it can be
used for other general purpose applications
too.

Functional 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
(programmable threshold).
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 10us @ 50Hz.
