High-speed signal processing

• JESD204串行接口

• Product Details:

  AD9683是一款14位ADC，最高采样速率250 MSPS，旨在为低成本、小尺寸、宽带宽、多功能通信应用提供解决方案。

  This ADC core adopts a multi-level, differential pipeline architecture and integrates output error correction logic. The ADC core has a wide bandwidth input and supports a variety of user-selectable input ranges. Integrated voltage reference simplifies design. The duty cycle stabilizer can be used to compensate for fluctuations in the ADC clock duty cycle, allowing the converter to maintain excellent performance. JESD204B high-speed serial interface reduces board routing requirements and reduces the number of pins required for the receiver device.

  ADC output data is sent directly to JESD204B serial output channel. These outputs are set to the CML level. Data can be sent over the channel at a maximum sample rate of 250 MSPS for a channel rate of 5 Gbps. The devices provide synchronous inputs (SYNCINB± and SYSREF±).

  Flexible power-down options can significantly reduce power consumption when needed. Programmable over-range level detection is supported via a dedicated fast detection pin.

  Setup and control programming is done using a three-wire SPI-compatible serial interface.

  The AD9683 is available in a 32-pin LFCSP package and is rated for an industrial temperature range of −40°C to +85°C. The product is protected by a U.S. patent.

  Product features:

  1. 集成14位、170 MSPS/250 MSPS ADC。
  2. 可配置的JESD204B输出模块支持最高5 Gbps的通道速率。
  3. 片内锁相环(PLL)允许用户提供单个ADC采样时钟，对应JESD204B数据速率时钟由PLL乘以该ADC采样时钟产生。
  4. 支持可选RF时钟输入以简化系统板设计。
  5. 取得专利的差分输入在最高至400 MHz的输入频率下仍保持出色的信噪比(SNR)性能。
  6. 采用1.8 V单电源供电。
  7. 标准串行端口接口(SPI)支持各种产品特性和功能，例如：控制时钟DCS、掉电模式、测试模式、基准电压模式、超量程快速检测以及串行输出配置等。
