AD9229: 4路、12位、50/65 MSPS、串行LVDS ADC

AD9229 功能框图AD9229是一款50 MSPS或65 MSPS、4路、12位模数转换器(ADC),内置串行LVDS输出和片内采样保持电路,专门针对低成本、低功耗、小尺寸和易用性而设计。该产品的转换速率最高可达65 MSPS,具有杰出的动态性能,适合小封装尺寸极为重要的应用。该ADC采用+3 V单电源供电。对于大多数应用来说,无需外部基准电压源或驱动器件。单独的输出电源引脚支持LVDS兼容型串行数字输出电平。为获得合适的LVDS串行数据速率,该ADC会自动倍乘采样速率时钟。该数据时钟输出(DCO)的工作频率高达390 MHz,支持双倍数据速率(DDR)操作。它还提供MSB触发器或帧时钟,用于发送新输出字节信号。该ADC支持省电模式,启用省电模式时,功耗为3 mW。AD9229采用先进的CMOS工艺制造,提供48引脚7 mm × 7 mm芯片级封装(48-LFCSP),额定温度范围为-40°C至+85°C工业温度范围。

The AD9229 is a 50 or 65 MSPS quad 12-bit, analog–to–digital converter with serial LVDS outputs. An on–chip track–and–hold circuit is designed for low cost, low power, small size and ease of use. The product operates up to a 65 MSPS conversion rate and is optimized for outstanding dynamic performance where a small package size is critical.The ADC requires a single +3 V power supply. No external reference or driver components are required for many applications. A separate output power supply pin supports LVDS compatible serial digital output levels.The ADC automatically multiplies up the sample rate clock for the appropriate LVDS serial data rate. This data clock output (DCO) provides operation up to 390 MHz and supports double-data rate operation (DDR). An MSB trigger or Frame clock is also provided to signal a new output byte. Power down is supported, and the ADC consumes 3 mW when enabled.Fabricated on an advanced CMOS process, the AD9229 is available in a 48-pin chip scale 7 mm x 7 mm package (48-LFCSP) specified over the industrial temperature range (–40°C to +85°C).
