说明

ADS54J64 器件是四通道、14 位、
1GSPS 模数转换器 (ADC),提供宽带宽、2倍过采样和高 SNR。ADS54J64 支持 JESD204B 串行接口,每个通道上具有 1 条信道,数据速率高达 10Gbps。经缓冲的模拟输入可在较宽频率范围内提供一致的阻抗,并最大程度降低采样保持干扰能量。ADS54J64 以超低功耗在较大输入频率范围内提供出色的无杂散动态范围 (SFDR)。数字信号处理块包含复频混频器,后接低通滤波器,低通滤波器具有 2 倍抽取率和 4 倍抽取率两个选项,支持高达 200MHz 的接收带宽。ADS54J64 还支持 DDC 旁路模式的 14 位、500MSPS 输出。

四通道 JESD204B 接口简化了连接,可实现高系统集成密度。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 位数据时所使用的位时钟。
