RF-Synthesizers-Slide10
For all ST RF synthesizers, there is a full product evaluation kit available which includes the evaluation board as well as a graphical user interface software for controlling the device and programming all of the device registers. ST also provides a versatile PLL simulator for evaluating how the device and evaluation board will perform under various conditions and configurations. Prior to designing a PC board, the designer can use these tools to help select the reference frequency, the phase detector frequency, the dividers to be used, and design the loop filters for the best performance for their particular application. As part of the kit, an eval board is provided which will allow full evaluation and real time measurements of the performance of the STuW81300 synthesizer. The STuW81300 eval board has on-board reference clock sources, as well as an input for an external reference clock. The eval board also has an input allowing use of an external VCO, and various outputs, differential or single-ended, for lower and higher frequency selections. The eval board also has a USB interface to allow connection via USB to a computer, for configuration and control of the STuW81300. Additionally, due to the integrated LDO voltage regulators, the eval board allows the STuW81300 to be supplied by a lab power supply or from the USB interface. USB is limited in the amount of power that it can provide and it is also noisy, there will be some limitations when powering the eval board from USB, but it is provided as an option.
