说明

ADC12DJ4000RF 器件是一款射频采样千兆采样模数转换器 (ADC),可对从直流到 10GHz 以上的输入频率进行直接采样。ADC12DJ4000RF 可配置为双通道 4GSPS ADC 或单通道 8GSPS ADC。支持高达 10GHz 的可用输入频率范围,可对频率捷变系统的 L、S、C 和 X 频带进行直接射频采样。

ADC12DJ4000RF 使用具有多达 16 个串行通道的高速 JESD204C 输出接口,支持高达 17.16Gbps 的线路速率。通过 JESD204C 子类 1 支持确定性延迟和多器件同步。JESD204C 接口可进行配置,对线路速率和通道数进行权衡。支持 8b/10b 和 64b/66b 数据编码方案。64b/66b 编码支持前向纠错 (FEC),可改进误码率。此接口向后兼容 JESD204B 接收器。

无噪声孔径延迟调节和 SYSREF 窗口等创新的同步特性可简化多通道应用的系统设计。提供可选的数字下变频器 (DDC),以便将数字信号频谱下变频到基带信号并降低接口速率。可编程 FIR 滤波器可实现片上均衡。
