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