SI4136 Datasheet (Silicon Laboratories)

SI4136, ISM RF SYNTHESIZER

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 in
