AD9879: 机顶盒、电缆调制解调器混合信号前端(MxFE®) |
AD9879是一款单电源电缆调制解调器/机顶盒混合信号前端，内置发射路径插值滤波器、完整正交数字上变频器和发射DAC。接收路径内置12位ADC、10位ADC和双通道7位ADC。内部需要的所有时钟和输出系统时钟均由PLL从单晶振或时钟输入产生。
AD9879是MxFE产品系列中的革新产品，属于极为成功的新一代AD9873产品。与AD9873相比，该器件成本更低，并有多项功能改进。这些改进包括：功耗更低；中频欠采样性能改进；输出增益控制以0.5 dB为步进，允许使用粗调增益输出驱动器；以及调谐分辨率(3.2 Hz)改进。此外，8位ADC已被7位器件所取代，以降低成本，但仍能提供充足的性能，可实现带外通道I&Q解调。
发射路径插值滤波器提供16倍的升采样系数，输出信号带宽高达8.3 MHz。直接数字频率合成器(DDS)可以产生最高65 MHz的载波频率，调谐分辨 ...More

发射路径插值滤波器提供16倍的升采样系数，输出信号带宽高达8.3 MHz。直接数字频率合成器(DDS)可以产生最高65 MHz的载波频率，调谐分辨率为26位。发射DAC的分辨率为12位，能以高达232 MSPS的采样速率工作。模拟输出可以在0 dB至7.5 dB范围内调整，步进为0.5 dB，以便在输出电平需要降低时保持信噪比(SNR)性能。
12位和10位中频ADC可以转换最高70 MHz的直接中频输入信号，采样速率最高可达33 MSPS。利用具有可调信号箝位电平的视频输入与10位ADC，该器件可以同时处理NTSC和QAM通道。
可编程Σ-Δ型DAC可用来控制可变增益放大器(VGA)或电压控制调谐器等外部器件。CA端口提供与AD8321/AD8323或AD8322/AD8327可编程增益放大器(PGA)电缆驱动器的接口，使主机处理器能通过MxFE SPORT实施控制。
AD9879采用100引脚MQFP封装。与引脚兼容产品AD9873相比，其接收路径欠采样性能更佳，成本更低。额定温度范围为-40ºC至+85ºC商用温度范围。
