\section{General Description}
The 7210 Clocker card is a 4hp EEM module.
It distrubites clock signal with \textless100 fs RMS jitter.
Clock input can be supplied to Clocker through the external SMA connector or the internal MMCX connector.
The input source can be selected using an SPDT switch.
Each card distributes the input to 10 outputs.
4 outputs are interfaced with SMA connectors, the other 6 are with MMCX connectors.
Clocker can be powered externally or internally.
To provide external power, connect an external 12V power source through the front panel power jack.
Otherwise, connect it to a carrier card (1124 Kasli or 1125 Kasli-SoC) using the EEM port.

\section{Electrical Specifications}
Specifications are derived based on the datasheets of
the clock buffer (ADCLK950BCPZ\footnote{\label{clock_buffer}https://www.analog.com/media/en/technical-documentation/data-sheets/ADCLK950.pdf}) \&
the RF transformer (TCM2-43X+\footnote{\label{rf_transformer}https://www.minicircuits.com/pdfs/TCM2-43X+.pdf}).
Clock output specifications is tested by supplying a 100 MHz DDS signal to the SMA input connector.
The output is connected to an oscilloscope with 50\textOmega~termination.

\section{Selecting Clock Source}
Clock input can be supplied to the 7210 Clocker using either the internal MMCX connector or the external SMA connector on the front panel.
The selection of clock input is configurable by a SPDT switch.
It is located between the MMCX input connector (\texttt{INT CLK IN}) and the MMCX output connectors.
\begin{multicols}{2}
Either INT or EXT can be selected.
\begin{itemize}
\itemsep0em
\item Internal MMCX (INT) \\
Clock signal from the MMCX connector \texttt{INT CLK IN} is distributed to all MMCX outputs.
\item External SMA (EXT) \\
Clock signal from the SMA connector \texttt{CLK IN} on the front panel is distributed to all MMCX outputs.
\end{itemize}

\section{Ordering Information}
To order, please visit \url{https://m-labs.hk} and select the 7210 Clocker in the ARTIQ Sinara crate configuration tool. The card may also be ordered separately by writing to \url{mailto:sales@m-labs.hk}.
