Hittite VCOs from Analog Devices now available in ADIsimPLL

Hi Robert

When can we have ADIsimPLL for Hittite PLLs?

John

We are currently working on this but I don't have a release date yet.

In the meantime, to simulate Hittite PLLs, use the free Hittite PLL Design Software.

1. Go here: http://hittite.com/products/view.html/view/HMC703LP4E
2. Click Software Download.
3. Fill out the short form. It is approved immediately.
4. You will receive an email with the download link.
5. When you download and run the software, click File > Load Hittite PLL Model File
6. Navigate to the PLL you want to simulate.

Hi.

If possible, could we get the following models added please?

HMC391LP4

HMC429LP4

HMC430LP4

HMC431LP4

HMC466LP4

HMC505LP4

HMC586LC4

Many thanks.

Done. See attachment above. It's probably best to delete v1.1 to avoid confusion.

Great, thanks. I'll check them out shortly.

Hi rbrennan,

I think I've discovered a bug with these.

If, for example you select the HMC391LP4E VCO in a design, complete the design but then use the Edit-->PLL Configuration option to change some parameters, you get a "VCO parameters updated" message.

This then deletes all phase noise and tuning data from the VCO and reverts to the default values (-300dBc/Hz PN, Kv = 10MHz/V and Tuning = 100-200MHz over 0-10V). This is then irreversible and you have to start a new design as the "select VCO" stage of the configuration disappears from the PLL Configuration menu.

I'm not sure whether this is a SimPLL bug or a bug with the VCO library? If it helps, whenever I go to Libraries-->Edit Current VCO or VCO Library Editor and open the Hittite library, all the VCO are listed as "Datasheet Kv" rather than "Table" and have the default values instilled.

Thanks

Hey FormerMember,

we're also very interested in having hitthite PLLs in ADISimpll!!

Do you have some more good news about a release date for this library update?
Meanwhile is it possible to have an unencrypted example format of the pll chip .lib, to generate a own lib with HMC70Xxx chips?

Big thanks

Andreas

Sorry, no release date yet. The only solution we currently have is the Hittite PLL Design Software option (mentioned above).

We working on this.

yeah, i know and use this matlab thing.. but it's not my favourite
