\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.\footnote{\label{clocker6}https://github.com/sinara-hw/Clocker/issues/6\#issuecomment-414048168}
|
|
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.
