AD9258是一款双通道、14位 、125 MSPS模数转换器(ADC),旨在支持需要高性能、低成本、小尺寸且具多功能性的通信应用。这款双通道ADC内核采用多级 、 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。ADC输出数据可以直接路由至两个外部14位输出端口,这些输出可以设置为1.8 V CMOS或LVDS。需要时,灵活的省电选项可以明显降低功耗。设置与控制的编程利用三线式SPI兼容型串行接口来完成。AD9258采用64引脚LFCSP封装,额定温度范围为−40°C至+85°C工业温度范围。
The AD9258 is a dual, 14-bit, 125 MSPS analog-to-digital converter (ADC). The AD9258 is designed to support communications applications where high performance, combined with low cost, small size, and versatility, is 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 that support a variety of user-selectable input ranges. An integrated voltage reference eases design consid-erations. A duty cycle stabilizer is provided to compensate for variations in the ADC clock duty cycle, allowing the converters to maintain excellent performance.
The ADC output data can be routed directly to the two external 14-bit output ports. These outputs can be set to either 1.8 V CMOS or LVDS.
Flexible power-down options allow significant power savings, when desired.Programming for setup and control is accomplished using a 3-wire SPI-compatible serial interface.The AD9258 is available in a 64-lead LFCSP and is specified over the industrial temperature range of −40°C to +85°
