Description
The Si4133W is a monolithic integrated circuit that performs RF and IF
synthesis for GSM/GPRS and W-CDMA wireless communications. In dual-
mode GSM/UMTS handsets, the Si4133W meets demanding requirements
for very low phase noise and fast settling time for both modes. Thehttp://www.DataSheet4U.net/ Si4133W
integrates three complete phase-locked loops (PLLs) on a single die
including VCOs, loop filters, reference and VCO dividers, and phase
detectors. Dividers and powerdown settings are programmable through a
three-wire serial interface.
