\section{General Description}
|
|
The 2238 MCX-TTL card is a 4hp EEM module.
|
|
It adds general-purpose digital I/O capabilities to carrier cards such as 1124 Kasli and 1125 Kasli-SoC.
|
|
|
|
Each card provides four banks of four digital channels each, with MCX connectors, controlled through 2 EEM connectors.
|
|
Each EEM connector controls two banks independently.
|
|
Single EEM operation is possible.
|
|
The direction (input or output) of each bank can be selected using DIP switches.
|
|
Each channel supports 50\textOmega~terminations individually controllable using DIP switches.
|
|
This card can achieve higher speed and lower jitter than the isolated 2118/2128 BNC/SMA-TTL cards.

\section{Electrical Specifications}

Both recommended operating conditions and electrical characteristics are based on the datasheet of the bus transceivers IC (74LVT162245MTD\footnote{\label{transceiver}https://www.onsemi.com/pdf/datasheet/74lvt162245-d.pdf}).

\section{Configuring IO Direction \& Termination}
|
|
The termination and IO direction can be configured by switches.
|
|
The per-channel termination and per-bank IO direction switches are found at the top and middle of the card respectively.
|
|
\begin{multicols}{2}
|
|
Termination switches selects the termination of each channel, between high impedence (OFF) and 50\textOmega~(ON).
|
|
|
|
IO direction switches partly decides the IO direction of each bank.
|
|
\begin{itemize}
|
|
\itemsep0em
|
|
\item Closed switch (ON) \\
|
|
Fix the corresponding bank to output. The direction cannot be changed by I\textsuperscript{2}C.
|
|
\item Opened switch (OFF) \\
|
|
Switch to input mode. The direction is input by default. Configurable by I\textsuperscript{2}C.
|
|
\end{itemize}

\section{Example ARTIQ code}
|
|
The sections below demonstrate simple usage scenarios of the 2245 LVDS-TTL card with the ARTIQ control system.
|
|
They do not exhaustively demonstrate all the features of the ARTIQ system.
|
|
The full documentation for the ARTIQ software and gateware is available at \url{https://m-labs.hk}.
|
|
|
|
Timing accuracy in the examples below is well under 1 nanosecond thanks to the ARTIQ RTIO system.
|
|
|
|
\subsection{One pulse per second}
|
|
The channel should be configured as output in both the gateware and hardware.
|
|
\inputcolorboxminted{firstline=9,lastline=14}{examples/ttl.py}
|
|
|
|
\subsection{Morse code}
|
|
This example demonstrates some basic algorithmic features of the ARTIQ-Python language.
|
|
\inputcolorboxminted{firstline=22,lastline=39}{examples/ttl.py}
|
|
|
|
\newpage
|
|
\subsection{Counting rising edges in a 1ms window}
|
|
The channel should be configured as input in both the gateware and hardware.
|
|
\inputcolorboxminted{firstline=47,lastline=52}{examples/ttl.py}
|
|
|
|
This example code uses the software counter, which has a maximum count rate of approximately 1 million events per second.
|
|
If the gateware counter is enabled on the TTL channel, it can typically count up to 125 million events per second:
|
|
\inputcolorboxminted{firstline=60,lastline=65}{examples/ttl.py}
|
|
|
|
\subsection{Responding to an external trigger}
|
|
One channel needs to be configured as input, and the other as output.
|
|
\inputcolorboxminted{firstline=74,lastline=80}{examples/ttl.py}
|

|
\section{Ordering Information}
|
|
To order, please visit \url{https://m-labs.hk} and select the 2238 MCX-TTL in the ARTIQ Sinara crate configuration tool. The card may also be ordered separately by writing to \url{mailto:sales@m-labs.hk}.
