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.
