Description

The Si4133 is a monolithic integrated circuit that performs both IF and dual-

band RF synthesis for wireless communications applications. The Si4133

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

detectors. Divider and power-down settings are programmable through a

three-wire serial interface.
