SI4122-D-GT数据手册集成电路（IC）的时钟发生器PLL频率合成器规格书PDF

描述 Description

Si4122-D-GT RF synthesizers perform IF and dual-band, low-noise RF frequency synthesis for wireless personal communications applications. Si4122-D-GT ICs address the price-sensitive, low-power, high-performance requirements for personal wireless communications by substantially reducing external passive component count, eliminating external VCOs and varactor diodes, improving power efficiency and isolating, in silicon, unwanted external interference. 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.
