"4-channel Wide-band PLL/VCO-based microwave frequency synthesiser" like on our ordering site is better than just "VCO/PLL"

use "4410/4412 DDS Urukul" instead of just "Urukul", since most of our datasheet has the part number prefix

Lower jitter and phase noise "than 4410/4412 DDS Urukul" (I think this is copied from the wiki)

Perhaps this should be moved to "Electrical Specifications" section as "lock time". Last time I checked, the lock time for ADF5355 and ADF5356 are 3.5ms and 1.7ms respectively

\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.

12GHz for Almazny as per hardware specs. 13.8 is theoretical max for ADF5356 but the whole RF path would have to support it, and it doesn't.

hmmm, should we also mention mirny max frequency is 6GHz? (12GHz/2) but the loop filter for ADF5356 mirny said it only supports up to 4.4GHz

4.4GHz is the safe config w/ the loop filter, but with Almazny you can go higher

also max max on Mirny output (regardless of the rest of the path) is 6.8

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.

the mirny & almazny are using the same ADF535X chips, so their lock time should be the same i.e. 1.7 ms when using ADF5356

to be slightly more precise, Almazny is taking the output B (2x) of the ADF535X, there's no extra/duplicate chip on the mezzanine
