AD9600:10位、105 MSPS/125 MSPS/150 MSPS、1.8 V双核模数转换器
AD9600是一款双核、10位、105 MSPS/125 MSPS/150 MSPS ADC,旨在支持要求低成本、小尺寸和多功能特性的通信应用。这款双核ADC采用多级、差分流水线架构,并集成了输出纠错逻辑。每个ADC均具有宽带宽、差分采样保持模拟输入放大器,支持用户可选的各种输入范围。集成基准电压源可简化设计。占空比稳定器可用来补偿ADC时钟占空比的波动,使转换器保持出色的性能。AD9600内置多种功能,可以简化通信接收机中的自动增益控制(AGC)功能。例如,快速检测特性可以通过输出四位输入电平信息实现快速检测超量程输入,并且延迟极短。此外,利用ADC的4个快速检测位,可编程阈值检测器可以监控传入信号的波幅,且延迟极短。如果输入信号电平超过可编程阈值,精调阈值上限指示器就会变为高电平。由于此阈值由四个最高有效位(MSB)设置,因此用户可以迅速调整系统增益,以避免发生超量程情况。AD9600的另一个AGC相关功能是信号监控器。该模块允许用户监控传入信号的复合幅度,这有助于设置增益以优化系统整体的动态范围。ADC输出数据可以直接路由至两个外部10位输出端口,这些输出可以设置为1.8 V至3.3 V CMOS或1.8 V LVDS。此外,灵活的省电选项可以明显降低功耗。
The AD9600 is a dual, 10-bit, 105 MSPS/125 MSPS/150 MSPS ADC. It is designed to support communications applications where low cost, small size, and versatility are desired.The dual ADC core features a multistage, differential pipelined architecture with integrated output error correction logic. Each ADC features wide bandwidth, differential sample-and-hold analog input amplifiers supporting a variety of user-selectable input ranges. An integrated voltage reference eases design considerations. A duty cycle stabilizer is provided to compen-sate for variations in the ADC clock duty cycle, allowing the converters to maintain excellent performance.The AD9600 has several functions that simplify the automated gain control (AGC) function in a communications receiver. For example, the fast detect feature allows fast overrange detection by outputting four bits of input level information with very short latency. In addition, the programmable threshold detector allows moni-toring the amplitude of the incoming signal with short latency, using the four fast detect bits of the ADC. If the input signal level exceeds the programmable threshold, the fine upper threshold indicator goes high. Because this threshold is set from the four MSBs, the user can quickly adjust the system gain to avoid an overrange condition.Another AGC-related function of the AD9600 is the signal monitor. This block allows the user to monitor the composite magnitude of the incoming signal, which aids in setting the gain to optimize the dynamic range of the overall system.The ADC output data can be routed directly to the two external 10-bit output ports. These outputs can be set from 1.8 V to 3.3 V CMOS or 1.8 V LVDS. In addition, flexible power-down options allow significant power savings.
