3 说明

ADC32RF42 器件是一款 14 位 1.5GSPS 双通道模数转换器 (ADC)，支持输入频率高达 4GHz 及以上的射频采样。ADC32RF42 专为高信噪比 (SNR) 设计，其噪声频谱密度为 –151.8dBFS/Hz，并可在较大输入频率范围提供动态范围和通道隔离。经缓冲的模拟输入配有片上端接电阻，可在较宽频率范围内提供统一输入阻抗并最大程度地降低采样和保持毛刺脉冲能量。

每个 ADC 通道均可连接到一个双频带数字下变频器 (DDC)，每个 DDC 最多连接三个独立的 16 位数控振荡器 (NCO) 用于相位相干跳频。此外，ADC 还配有前端峰值和 RMS 功率检测器及报警功能，用以支持外部自动增益控制 (AGC) 算法。

ADC32RF42 支持具有基于子类 1 确定性延迟的 JESD204B 串行接口，其数据速率高达 12.5Gbps，每个 ADC 最多具有四条信道。该器件采用 72 引脚 VQFN 封装 (10mm × 10mm)，支持工业级温度范围（-40℃ 至 +85°C）。
