\section{General Description}
The 5432 Zotino is a 4hp EEM module part of the ARTIQ Sinara family.
It adds digital-analog converting capabilities to carrier cards such as 1124 Kasli and 1125 Kasli-SoC.
It provides 4 groups of 8 analog channels each, exposed by 1 HD68 connector.
Each channel supports output voltage from -10 V to 10 V.
All channels can be updated simultaneously.
Channels can broken out to BNC, SMA or MCX by adding external 5518 BNC-IDC, 5528 SMA-IDC or 5538 MCX-IDC cards.

\section{Electrical Specifications}
% \hypersetup{hidelinks}
% \urlstyle{same}
The specifications are based on the datasheet of the DAC IC
(AD5372BCPZ\footnote{\label{dac}https://www.analog.com/media/en/technical-documentation/data-sheets/AD5372\_5373.pdf}),
and various information from Sinara wiki\footnote{\label{zotino_wiki}https://github.com/sinara-hw/Zotino/wiki}.

The following are cross-talk and transient behavior of Zotino\footnote{\label{zotino21}https://github.com/sinara-hw/Zotino/issues/21}.
In terms of output noise, it was measured after 15 cm IDC cable, IDC-SMA, 100 cm coax ($\sim$50 pF), and 500 k$\Omega$ $||$ 150 pF\footnote{\label{zotino27}https://github.com/sinara-hw/Zotino/issues/27}.
The DAC output during noise measurement is 3.5 V.

\item CH1 as aggressor, CH0 as victim
\item CH0, 2-7 terminated, CH 8-31 open
\item Aggressor signal from BNC passed through 15cm IDC26, 2m HD68-HD68 SCSI-3 shielded twisted pair, 15cm IDC26, converted back to BNC with adapters between all different cables \& connectors.

\section{Example ARTIQ code}
The sections below demonstrate simple usage scenarios of the 5432 DAC Zotino 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}.
\subsection{Set output voltage}
The following example initializes the Zotino card, then emits 1.0 V, 2.0 V, 3.0 V and 4.0 V at channel 0, 1, 2, 3 respectively.
Voltages of all 4 channels are updated simultaneously with the use of \texttt{set\char`_dac()}.
\inputcolorboxminted{firstline=11,lastline=22}{examples/zotino.py}
\newpage
\subsection{Triangular Wave}
A triangular waveform at 10 Hz, 16 V peak-to-peak.
Timing accuracy of the RTIO system can be demonstrated by the precision of the frequency.
Import \texttt{scipy.signal} and \texttt{numpy} modules to run this example.

\section{Ordering Information}
To order, please visit \url{https://m-labs.hk} and select the 5432 DAC Zotino in the ARTIQ Sinara crate configuration tool. The card may also be ordered separately by writing to \url{mailto:sales@m-labs.hk}.
