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。
Full featured evaluation board for the AD9139
AD9139-EBZ includes options to evaluate single output
AD9139-DUAL-EBZ includes options to evaluate:
DAC only (I & Q DAC output)
DAC and ADL537X quadrature modulator
USB interface for configuration
Internal or external power supply regulation
Data pattern generator and SPI software interfaces
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.
