SI4122 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. Divider and power-down settings are programmable through a three-wire serial interface.
