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. The 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.
