The AD9430 is a 12-bit monolithic sampling analog-to-digital converter optimized for high performance, low power, and ease of use. The product operates up to a 210 MSPS conversion rate and is optimized for outstanding dynamic performance in wideband carrier and broadband systems. All necessary functions, including a track-and-hold (T/H) and reference are included on the chip to provide a complete conversion solution.
The ADC requires a 3.3 V power supply and a differential ENCODE clock for full performance operation. The digital outputs are TTL/CMOS or LVDS compatible and support either twos complement or offset binary format. Separate output power supply pins support interfacing with 3.3 V or 2.5 V CMOS logic.
Two output buses support demultiplexed data up to 105 MSPS rates in CMOS mode. A data sync input is supported for proper output data port alignment in CMOS mode and a data clock output is available for proper output data timing. In LVDS mode, the chip provides data at the ENCODE clock rate.
Fabricated on an advanced BiCMOS process, the AD9430 is available in a 100-lead surface-mount plastic package (100 e-PAD TQFP) specified over the industrial temperature range (-40°C to +85°C).
AD9430是一款12位单芯片采样模数转换器(ADC),专门针对高性能、低功耗和易用性进行了优化。该产品的转换速率最高可达210 MSPS,具有杰出的动态性能,适合宽带载波和宽带系统使用。芯片上集成了全部必需功能,包括采样保持(T/H)与基准电压源,可提供完整的信号转换解决方案。
该ADC要求采用3.3 V电源供电及差分ENCODE时钟信号,以便充分发挥其工作性能。数字输出为TTL/CMOS兼容或LVDS兼容,支持二进制补码或偏移二进制格式。单独的输出电源引脚支持3.3 V或2.5 V CMOS逻辑接口。
在CMOS模式下,双输出总线支持最高105 MSPS速率的解复用数据。支持数据同步输入,确保CMOS模式下正确对准输出数据端口,并提供数据时钟输出,以确保正确的输出数据时序。在LVDS模式下,芯片采用ENCODE时钟速率提供数据。
AD9430采用先进的BiCMOS工艺制造,提供100引脚表面贴装塑料封装(100 e-PAD TQFP),额定温度范围为-40°C至+85°C工业温度范围。
