Shown on this slide is a chart comparing the STW81200 specifications to some of the competition. Reviewing this chart, ST certainly compares well with all of them, either equal to or better in phase noise performance. ST has a lot of other features that the competition does not have such as high levels of integration, the embedded LDOs, and the dual outputs. ST also offers additional flexibility; if for some reason the designer wanted to use an external VCO with the device, it is flexible enough to allow that. Other features include low power modes and a flexible power supply, as well as a small package.
