\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}}),
(ADF5356\footnote{\label{adf5356}\url{https://www.analog.com/media/en/technical-documentation/data-sheets/ADF5356.pdf}} for 4456 Mirny, ADF5355\footnote{\label{adf5355}\url{https://www.analog.com/media/en/technical-documentation/data-sheets/ADF5355.pdf}}) for 4457 Almazny),
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}}.
