Description

The Si4133G-X2 is a monolithic integrated circuit that performs both IF and

dual-band RF synthesis for GSM and GPRS wireless communications

applications. The Si4133G-X2 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.
