Texas Instruments ADC3x高速12/14位ADC
Texas Instrument ADC3x 高速 12/14 位模数转换器属于高线性、超低功耗、双通道、12 或 14 位、25MSPS 至 125MSPS 模数转换器(ADC)。这些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。输入时钟分频器提高了系统时钟架构的设计灵活性,SYSREF输入实现整个系统的同步。ADC3x支持串行低压差分信号(LVDS)接口,从而减少接口线路的数量,实现高系统集成度。串行 LVDS 接口为双线制,通过两个 LVDS 对,串行化并输出每个 ADC 数据。内部锁相环(PLL)会将传入的ADC采样时钟倍频,以获得串行输出各通道的12或14位数据时所使用的位时钟。特性
