The Si4133/Si4133G synthesizer family evaluation board is a complete, PC-based evaluation platform for the following Silicon Laboratories devices and their derivatives. The board includes all support circuitry necessary to evaluate the synthesizer including a reference clock, SMA connections for external measurement equipment, and an interface to a personal computer for controlling the device. The PC software is a graphical, easy-to-use interface that allows the user to directly enter frequencies, set divider ratios, and toggle power control options by a parallel port connection. A PC and power supply are all that is needed for a complete evaluation system.
