The Si4133 is a monolithic integrated circuit that performs IF and dual-band, low-
noise RF frequency synthesis for wireless personal communications applications.
The Si4133 addresses the price-sensitive, low-power, high-performance require-
ments for personal wireless communications by substantially reducing external
passive component count, eliminating external VCOs and external varactor
diodes, improving power efficiency, and isolating, in silicon, unwanted external
interference. The stable, low-phase noise characteristics are achieved through a
proprietary self-tuning architecture that does not require external adjustments or
laser trimming for component-tolerance matching.
and VCO dividers, and phase detectors. Variables for dividers, phase detector gain
settings, and power-down settings are programmable through a three-wire serial
interface (Data, Clock, and Enable) and a 22-bit internal shift register.
