3 说明

ADC344x 器件属于高线性度、超低功耗、四通道、14 位、25MSPS 至 125MSPS 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。输入时钟分频器可给予系统时钟架构设计更高的灵活性，同时 SYSREF 输入可实现整个系统同步。

ADC344x 系列支持串行低压差分信令 (LVDS)，从而减少接口线路的数量，实现高系统集成密度。串行 LVDS 接口为双线制，通过两个 LVDS 对串行输出每个 ADC 数据。此外，也可提供单线制串行 LVDS 接口。内部锁相环 (PLL) 会将传入的 ADC 采样时钟加倍，以获得串行输出各通道的 14 位输出数据时所使用的位时钟。除了串行数据流之外，数据帧和位时钟也作为 LVDS 输出进行传送。
