PLL Clock Generators | NBC12430
概览
NBC12430 和 NBC12430A 为通用型、基于 PLL 的合成时钟源。VCO 的运行频率范围为 400 MHz 至 800 MHz。VCO 频率发送到 N 输出分频器，此时可以将其配置为提供 1、2、4 或 8 分频比。VCO 和输出频率可使用配置逻辑的并行或串行接口进行编程。使用 16 MHz 晶体可实现 250 KHz、500 KHz、1.0 MHz、2.0 MHz 的输出频率，具体取决于输出分频器设置。完全集成了 PLL 环路滤波器，无需任何外部组件。 NBC12430 规定运行范围为商用温度范围。 NBC12430A 规定运行范围为工业温度范围。
