Product Details:
AD9690是一款14位、1 GSPSanalog-to-digital converter(ADC)。该器件内置片内缓冲器和采样保持电路，专门针对低功耗、小尺寸和易用性而设计。该器件设计用于高达2 GHz的宽带模拟信号采样。 AD9690针对宽输入带宽、高采样速率、出色的线性度和小封装低功耗而优化。

这款ADC内核采用多级、差分流水线架构，并集成了输出纠错逻辑。该ADC具有宽带宽输入，支持用户可选的各种输入范围。集成基准电压源可简化设计。

模拟输入和时钟信号均为差分输入信号。 ADC数据输出内部连接到两个数字下变频器(DDC)。每个DDC均含有四个级联信号处理级：一个12位频率转换器(NCO)和四个半带抽取滤波器。

除了DDC模块，AD9690还具备其他功能，能够简化通信接收机的自动增益控制(AGC)。利用ADC的快速检测输出位，可编程阈值检测器可以监控输入信号功率。如果输入信号电平超过可编程阈值，快速检测指示器就会变为高。由于该阈值指示器的延迟极短，因此用户能够快速调低系统增益，从而避免ADC输入端出现超量程现象。

用户能将子类1 JESD204B高速串行输出配置为1、2或4通道，具体取决于DDC配置和接收逻辑器件的可接受通道速率。通过SYSREF±和SYNCINB±输入引脚，可提供多器件同步支持。

AD9690具有灵活的掉电选项，在需要时可以明显降低功耗。这些特性均可通过1.8 V至3.3 V三线式SPI进行编程。

AD9690采用64引脚无铅LFCSP封装，额定温度范围为-40℃至+85℃工业温度范围。该产品受美国专利保护。

Product features:
1. 较宽的全功率带宽，支持高达2 GHz的IF信号采样
2. 提供可编程输入端的缓冲输入简化了滤波器设计和实施。
3. 两个集成式宽带抽取滤波器和数控振荡器(NCO)模块支持多频段接收器。
4. 灵活的串行端口接口(SPI)控制各种产品特性和功能，满足特定系统要求。
5. 可编程快速超量程检测。
6. 9 mm × 9 mm、64引脚LFCSP。
