Description
The Si4133 is a monolithic integrated circuit that performs both IF and dual-
band RF synthesis for wireless communications applications. The Si4133
includes three VCOs, loop filters, reference and VCO dividers, and phase
detectors. Divider and powerdown settings are programmable with a three-
wire serial interface.

PWDN pin is high, power management is in control of the 27 nH Powerdown register bits The IF and RF sections of the Si4133 circuitry can be individually powered down by setting the Powerdown register bits PDIB and PDRB low, respectively.

... Si4133 Auxiliary Output (AUXOUT) The signal appearing on AUXOUT is selected by setting the AUXSEL bits in the Main Configuration register (Register 0). The LDETB signal can be selected by setting the AUXSEL bits to 11. This signal can be used to indicate that the PLL is going to lose lock because of excessive ambient temperature drift and should be re-tuned. The LDETB signal indicates a logical OR result if both IF and RF are simultaneously generating a signal ...
