Description

The Si2200 is a monolithic integrated circuit that performs both IF and RF

synthesis for wireless communications applications. The Si2200 includes

three VCOs, loop filters, reference and VCO dividers, and phase

detectors. Divider and powerdown settings are programmable through a

three-wire serial interface.
