+\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.
