AD9857/PCB开发板套件编程器的射频评估开发套件开发板规格书PDF中文资料

AD9857/PCB属于开发板套件编程器的射频评估开发套件开发板。由亚德诺半导体技术有限公司制造生产的AD9857/PCB射频评估和开发套件，开发板本系列中的产品适用于在已知实施环境中，提供能访问射频相关器件的功能或者有助于访问该功能。所含的焦点产品范围从射频信号链元器件（如放大器和检测器）到模块化收发器，以及不直接包含焦点产品的适配器硬件，但此类硬件可供方便地访问用户单独提供的特定射频产品或系列。

GENERAL DESCRIPTION

The AD9857 integrates a high speed direct digital synthesizer (DDS), a high performance, high speed, 14-bit digital-to-analog converter (DAC), clock multiplier circuitry, digital filters, and other DSP functions onto a single chip, to form a complete quadrature digital upconverter device. The AD9857 is intended to function as a universal I/Q modulator and agile upconverter, single-tone DDS, or interpolating DAC for communications applications, where cost, size, power dissipation, and dynamic performance are critical attributes.
