+\section{General Description}
+The 7210 Clocker card is a 4hp EEM module.
+It distrubites clock signal with \textless100 fs 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.

+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}
