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 powerdown settings are programmable with a three-
wire serial interface.
