SI4112 - DUAL-BAND RF SYNTHESIZER

Download the SI4112 datasheet PDF. This datasheet also covers the SI4133 variant, as both devices belong to the same dual-band rf synthesizer family and are provided as variant models within a single manufacturer datasheet.

General Description

The Si4133 is a monolithic integrated circuit that performs both IF and dualband RF synthesis for wireless communications applications.

The Si4133 includes three VCOs, loop filters, reference and VCO dividers, and phase detectors.
