 \section{General Description}
-The 4456 Synthesizer Mirny card is a 4hp EEM module, part of the ARTIQ/Sinara family. It adds microwave generation capabilities to carrier cards such as 1124 Kasli and 1125 Kasli-SoC.
+    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.
 
-It provides 4 channels of PLL frequency synthesis. Output frequencies from 53 MHz to \textgreater 4 GHz are supported.The range can be expanded up to 13.6 GHz with the Almazny mezzanine (4467 HF Synthesizer).
