\section{Electrical Specifications}

    % \hypersetup{hidelinks}
    % \urlstyle{same}
    These specifications are based on the datasheet of the DAC IC
    (AD5542\footnote{\label{dac}\url{https://www.analog.com/media/en/technical-documentation/data-sheets/AD5512A_5542A.pdf}}),
    and various information from the Sinara wiki\footnote{\label{fastino_wiki}\url{https://github.com/sinara-hw/Fastino/wiki}}.

    \dag Note that current QUARTIQ gateware supports 2.55 MSPS maximum.

    The following table records cross-talk and transient behavior by Fastino, collected in various Sinara issues, see spur analysis\footnote{\label{fastino56}\url{https://github.com/sinara-hw/Fastino/issues/56}}, cross-talk\footnote{\url{https://github.com/sinara-hw/Fastino/issues/85}}, and noise summary\footnote{\url{https://github.com/sinara-hw/Fastino/issues/51}}. DAC output during output noise measurement was 6.875 V, updating continuously, channel 27 used for recording.

\newpage

\section{LEDs}

    5632 DAC Fastino provides eight user LEDs in the front panel. These are directly accessible with ARTIQ RTIO. Four additional LEDs indicate, respectively, power good (\texttt{PG}), FPGA done (\texttt{FD}), overtemperature (\texttt{OT}), and gateware or initialization error (\texttt{ERR}).

\sysdescsection

    5632 DAC Fastino should be entered in the \texttt{peripherals} list of the corresponding core device in the following format:

    \begin{tcolorbox}[colback=white]
        \begin{minted}{json}
            {
                "type": "fastino",
                "ports": [0],
                "log2_width": 0 // select 0 to 5, default is 0
            }
        \end{minted}
    \end{tcolorbox}

    Replace 0 with the EEM port used on the core device. Any port may be used on the core device side. Fastino provides two EEM ports, of which ARTIQ always requires the first, \texttt{EEM0}. The second, \texttt{EEM1}, should not be used.

    The \texttt{log2\_width} field accepts a number from 0 to 5 inclusive and represents (in powers of two) the number of DAC channels packed into a single RTIO write (1 to 32). This allows and defines the use of \texttt{set\_group()} functions rather than \texttt{set\_dac()} as in examples given below.

    \subsection{CIC interpolators}

    Fastino gateware features dynamically configurable CIC (cubic B-spline) interpolators, defined individually by channel, with interpolation rates from 1 (2.55 MSPS) to 65536 (39 SPS). For more details, see manual documentation on ARTIQ driver functions \texttt{stage\_cic} and \texttt{apply\_cic}.
