AD9139-DUAL-EBZ 是 Analog Devices（亚德诺半导体）推出的一款高速信号处理数模转换器（DAC）评估板，专为快速评估 AD9139 双通道应用而设计。由于 AD9139 本身是单通道转换器，该评估板集成了两颗 AD9139 芯片，分别作为 I（同相）和 Q（正交）通道，适用于宽带基带 I/Q 发射器设计。
核心特性与规格
主要功能：用于评估 16 位、1.6 GSPS 的高速 DAC AD9139，支持多芯片同步功能，可实现高达 1150 MHz 的超宽 I/Q 带宽。
板载组件：包含时钟分配芯片 AD9516（用于 DACCLK、REFCLK 等时钟的扇出和分频）以及正交调制器 ADL5375，便于进行 DAC+IQMOD 的快速评估。
电源要求：采用 +5V 电源供电。
接口类型：支持灵活的 16 位 LVDS 接口。
工作温度：-40°C 至 +85°C。
配套工具与连接
该评估板通常需连接 数字模式发生器（DPG2/3） 使用，DPG3 可自动格式化数据并发送至评估板，简化器件评估流程。用户还需配合使用 SPI 配置软件（AD9139 DUAL SPI）和 DPG Downloader 软件进行寄存器配置和波形生成。

Product Details
The AD9139-EBZ connects to a ADS7-V2EBZ or SDP-H1 for quick evaluation of the AD9139, a high-speed, signal processing Digital to Analog Converter. The ADS7-V2EBZ or SDP-H1 automatically formats the data and sends it to the AD9139-EBZ, simplifying evaluation of the device. The Evaluation Board (EVB) runs from a +5V supply. A clock distribution chip AD9516 is included on this EVB as a clock fan-out and frequency divider for the DACCLK, REFCLK and ADS7-V2EBZ or SDP-H1 input clock.

Also included is a quadrature modulator ADL5375 for quick DAC+IQMOD evaluation. Since AD9139 is a single channel converter, dual AD9139s are used on the board to work as I and Q, which typically applies to the case of wideband applications.
