\section{General Description}
    The 4456 Synthesizer Mirny card is a 4hp EEM module; the 4457 HF Synthesizer Mirny + Almazny card, consisting of 4456 Mirny plus the 4-channel Almazny HF mezzanine, is a 8hp EEM module. Both Synthesizer cards add microwave generation capabilities to carrier cards such as 1124 Kasli and 1125 Kasli-SoC.

    Both cards provide 4 channels of PLL frequency synthesis. 4456 Synthesizer Mirny supports output frequencies from 53 MHz to \textgreater 4GHz. As 4457 HF Synthesizer with Almazny mezzanine this range is expanded up to 13.6 GHz.

    Each channel can be attenuated from 0 to -31.5 dB by a digital attenuator. RF switches on each channel provide at least 50 dB isolation.

\section{Electrical Specifications}

    Specifications of parameters are based on the datasheets of the PLL IC
    (ADF5356\footnote{\label{adf5356}\url{https://www.analog.com/media/en/technical-documentation/data-sheets/ADF5356.pdf}}),
    clock buffer IC (Si53340-B-GM\footnote{\label{clock_buffer}\url{https://www.skyworksinc.com/-/media/Skyworks/SL/documents/public/data-sheets/si5334x-datasheet.pdf}}),
    and digital attenuator IC (HMC542BLP4E\footnote{\label{attenuator}\url{https://www.analog.com/media/en/technical-documentation/data-sheets/hmc542b.pdf}}).
    Test results are from Krzysztof Belewicz's thesis. "Microwave synthesizer for driving ion traps in quantum computing"\footnote{\label{mirny_thesis}\url{https://m-labs.hk/Krzysztof\_Belewicz\_V1.1.pdf}}.

    Phase noise performance of 4456 Mirny was tested using the ADF4351 evaluation kit\repeatfootnote{mirny_thesis}. The SPI signal was driven by the evaluation kit, converted into LVDS signal by propagating through the DIO-tester card, finally arriving at the Mirny card. 4456 Mirny was then connected to the RSA5100A spectrum analyzer for measurement.

    Noise response spike can be improved by inserting an additional common-mode choke between the power supply and Mirny; note that this common-mode choke is not present on the card itself. The following is a comparison between the two setups at 1 GHz output:

        \item Blue: CM choke added with an 100 \textmu F capacitor after the CM choke

    Phase noise at different output frequencies is then measured:

\section{Programmable LEDs}

    4456 Mirny features several status LEDs, including a two per output channel. One per channel displays RF switch status.

    The 4457 Almazny mezzanine features an additional row of LEDs, one per output channel, without a fixed purpose. The associated ARTIQ module allows programming these directly through the channel \texttt{set} method.

\newpage
\sysdescsection

    4456 Synthesizer Mirny must be entered in the \texttt{peripherals} list of the corresponding core device in the following format:

    \begin{tcolorbox}[colback=white]
        \begin{minted}{json}
            {
                "type": "mirny",
                "ports": 0,
                "clk_sel": "mmcx", // optional
                "refclk": 125e6 // optional
            }
        \end{minted}
    \end{tcolorbox}

    Replace 0 with the EEM port number used on the core device. Any port can be used. The \texttt{clk\_sel} field is optional and may be specified as one of either \texttt{xo}, \texttt{mmcx}, or \texttt{sma}. The default is \texttt{xo}. The \texttt{refclk} field is optional and the default is \texttt{100e6}.

    For 4457 Mirny + Almazny, one field must be added:

    \begin{tcolorbox}[colback=white]
        \begin{minted}{json}
            {
                "type": "mirny",
                "almazny": true,
                "ports": 0
            }
        \end{minted}
    \end{tcolorbox}

\codesection{4456 Synthesizer Mirny and 4457 Mirny + Almazny}

    \subsection{1 GHz sinusoidal wave}
    Generates a 1 GHz sinusoid from RF0 with full scale amplitude, attenuated by 12 dB. Both the CPLD and the PLL channels should be initialized.

    \inputcolorboxminted{firstline=10,lastline=17}{examples/pll.py}

    \subsection{Almazny paired output}

    Mirny and Almazny output channels are paired, and Almazny output channels output twice the frequency of the main Mirny outputs. To set Almazny HF outputs for 4457 HF Synthesizer, set the Mirny outputs to one-half the desired frequency. The above code, run with 4457 HF Synthesizer, will also output 2GHz from Almazny HF0.

    \subsection{ADF5356 power control}
    Output power can be controlled be configuring the PLL channels individually in addition to the digital attenuators. After initialization of the PLL channel (ADF5356), the following line of code can change the output power level:

    \inputcolorboxminted{firstline=28,lastline=28}{examples/pll.py}

    The parameter corresponds to a specific change of output power according to the following table\repeatfootnote{adf5356}.

    \begin{center}
        \captionof{table}{Power changes from ADF5356}
        \begin{tabular}{|c|c|}
        \hline
        Parameter & Power \\ \hline
        0 & -4 dBm \\ \hline
        1 & -1 dBm \\ \hline
        2 & +2 dBm \\ \hline
        3 & +5 dBm \\ \hline
        \end{tabular}
    \end{center}

    ADF5356 gives +5 dBm by default. The stored parameter in ADF5356 can be read using the following line"

    \inputcolorboxminted{firstline=29,lastline=29}{examples/pll.py}

    \subsection{Periodic 100\textmu s pulses}
    The output can be toggled on and off periodically using the RF switches. The following code emits a 100\textmu s pulse in every millisecond. A microwave signal should be programmed in prior (such as the 1 GHz wave example).
