3 说明

ADC32J2x 属于高线性度、超低功耗、双通道、12 位、50MSPS 至 160MSPS 模数转换器 (ADC) 系列。 此类器件专门设计用于支持具有宽动态范围需求且要求苛刻的高输入频率信号。 时钟输入分频器可给予系统时钟架构设计更高的灵活性,SYSREF 输入可实现整个系统同步。 该器件支持 JESD204B 接口,从而减少接口线路的数量,实现高系统集成度。 JESD204B 接口是串行接口,仅通过一个差分对即可串行输出每个 ADC 的数据。 内部锁相环 (PLL) 会将传入的 ADC 采样时钟乘以 20,以获得串行输出各通道的 12 位数据时所使用的位时钟。 该器件支持子类 1,接口速率高达 3.2Gbps。
