AD9287BCPZ-100: 4路、8位、100 MSPS、串行LVDS、1.8 V ADC

The AD9287 is a quad, 8-bit, 100 MSPS analog-to-digital converter (ADC) with an on-chip sample-and-hold circuit designed for low cost, low power, small size, and ease of use. The product operates at a conversion rate of up to 100 MSPS and is optimized for outstanding dynamic performance and low power in applications where a small package size is critical.

The ADC requires a single 1.8 V power supply and LVPECL-/ CMOS-/LVDS-compatible sample rate clock for full performance operation. No external reference or driver components are required for many applications.

The ADC automatically multiplies the sample rate clock for the appropriate LVDS serial data rate. A data clock output (DCO) for capturing data on the output and a frame clock output (FCO) for signaling a new output byte are provided. Individual-channel power-down is supported and typically consumes less than 2 mW when all channels are disabled.

The ADC contains several features designed to maximize flexibility and minimize system cost, such as programmable clock and data alignment and programmable digital test pattern generation. The available digital test patterns include built-in deterministic and pseudorandom patterns, along with custom user-defined test patterns entered via the serial port interface (SPI).

The AD9287 is available in an RoHS compliant, 48-lead LFCSP. It is specified over the industrial temperature range of -40°C to +85°C.

AD9287是一款4路、8位、100 MSPS模数转换器(ADC),内置片内采样保持电路,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100 MSPS,具有杰出的动态性能与低功耗特性,适合小封装尺寸极为重要的应用。

该ADC要求采用1.8 V单电源供电以及LVPECL-/ CMOS-/LVDS-兼容型采样速率时钟信号,以便充分发挥其工作性能。对于大多数应用来说,无需外部基准电压源或驱动器件。

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。它提供一个数据时钟输出(DCO)用于在输出端捕获数据,以及一个帧时钟输出(FCO)用于发送新输出字节信号。它还支持各通道单独进入省电状态;禁用所有通道时,典型功耗低于2 mW。

该ADC内置多种功能特性,可使器件的灵活性达到最佳、系统成本最低,例如可编程时钟与数据对准、生成可编程数字测试码等。可获得的数字测试码包括内置的确定性码和伪随机码,以及通过串行端口接口(SPI)输入的用户自定义测试码。

AD9287采用符合RoHS标准的48引脚LFCSP封装,额定温度范围为-40°C至+85°C工业温度范围。
