Features

Applications

Description

The Si4133G is a monolithic integrated circuit that performs both IF and

dual-band RF synthesis for GSM and GPRS wireless communications

applications. The Si4133G 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.
