Description
The Si4136 is a monolithic integrated circuit that performs both IF and RF
synthesis for wireless communications applications. The Si4136http://www.DataSheet4U.net/ includes
three VCOs, loop filters, reference and VCO dividers, and phase detectors.
Divider and powerdown settings are programmable through a three-wire
serial interface.
