AD9864: 中频数字化子系统 |
AD9864*是一款通用中频子系统，可对信号带宽范围为6.8 kHz至270 kHz的低电平10 MHz至300 MHz中频输入进行数字化处理。AD9864的信号链包括一个低噪声放大器(LNA)、一个混频器、一个带通Σ-Δ型模数转换器(ADC)以及一个具有可编程抽取系数的抽取滤波器。自动增益控制(AGC)电路提供12 dB的连续增益调整。辅助模块包括时钟和LO频率合成器。
AD9864的高动态范围和带通Σ-Δ型转换器内在的抗混叠功能，使该器件能处理比目标信号强度高达95 dB的阻塞信号。此特性可以降低中频滤波要求，从而降低无线电的成本，而且还支持不同通道带宽的多模无线电，使中频滤波器具有最大的额定通道带宽。
通过SPI®端口可对AD9864的许多参数进行编程，因此该器件可针对特定应用进行优化。可编程参数包括：频率合成器分频比、AGC衰减和上升/延迟时间、接收 ...More
