双通道中频接收机

AD6643是一款11位、200 MSPS/250 MSPS、双通道中频(IF)接收机，专门针对要求高动态范围性能、低功耗和小尺寸的电信应用中支持多通道系统而设计。\n\n 该器件包括两个高性能模数转换器(ADC)和噪声整形再量化器(NSR)数字模块。每个ADC由多级、差分流水线架构组成，并集成了输出纠错逻辑，每个ADC差分流水线的第一级包含一个宽带宽开关电容采样网络。集成基准电压源可简化设计考量。占空比稳定器(DCS)补偿ADC时钟占空比的波动，使转换器保持出色的性能。\n\n 各ADC的输出内部连接到NSR模块。集成NSR电路能够提高奈奎斯特带宽内较小频段的信噪比(SN • 每个通道11位、250 MSPS输出数据速率\n\n• NSR使能时的性能\n• NR：74.5 dBFS（55 MHz频段、最高90 MHz、250 MSPS）\n\n• SNR：72.0 dBFS（82 MHz频段、最高90 MHz、250 MSPS）\n\n\n\n\n• NSR禁用时的性能\n• SNR：66.2 dBFS（最高90 MHz、250 MSPS）\n\n• SFDR：85 dBc（最高185 MHz、250 MSPS）\n\n\n\n\n• 总功耗：706 mW (200 MSPS)\n\n• 1.8 V电源电压;
