BU2630FV集成电路（IC）的时钟发生器PLL频率合成器规格书PDF中文资料

BU2630FV属于集成电路（IC）的时钟发生器PLL频率合成器。由罗姆半导体集团制造生产的BU2630FV时钟发生器，PLL，频率合成器时钟发生器、PLL 和频率合成器集成电路 (IC) 可为逻辑器件提供参考信号的稳定定时脉冲，这些器件包括计算机、微控制器、数据通信系统和图形/视频发生器。这些集成电路可能包括缓冲器、驱动器、分频器、倍频器、多路复用器、合成器、扇出分配器和预分频器。

The BU2630F/BU2630FV are a CMOS LSI with an internal dual PLL synthesizer.

VCOs for transmission and reception can be controlled independently, and the reference frequency and main counter settings can also be programmed separately. This product is designed for applications involving cordless telephones and communications equipment worldwide.
