AD9508- 1.65 GHz时钟扇出缓冲器，集成输出分频器和延迟调整
AD9508提供时钟扇出能力，针对能使系统性能达到最佳的低抖动进行设计。这款器件能满足数据转换器时钟等应用所需的相位噪声和低抖动要求，可优化这些应用的性能。
它集成4个独立的差分时钟输出，每一个输出都支持数种逻辑电平类型，包括：LVDS (1.65 GHz)、HSTL (1.65 GHz)和1.8V CMOS (250 MHz)。在1.8V CMOS输出模式下，差分输出转换为两个CMOS单端信号。无论电源电压如何改变，CMOS输出始终为1.8 V逻辑电平。
每路输出都有一个可编程分频器，可以旁路该分频器或者设置最高1024的整数分频比。此外，AD9508还支持输出相位在输出之间进行粗调。
上电时，还可对器件进行各种固定配置的引脚编程，从而无需进行SPI或I2C编程。
AD9508提供24引脚LFCSP封装，可以采用3.3 V单电源 更多
