AD9958/PCB开发板套件编程器的评估演示板及套件规格书PDF中文资料

AD9958/PCB属于开发板套件编程器的评估演示板及套件。由亚德诺半导体技术有限公司制造生产的AD9958/PCB评估和演示板及套件该系列产品提供了一种方便的方法，在经过验证的实施环境中评估某些重点器件的性能或特性。评估方法通常有完善的文档说明，并且视乎具体情况由评估软件提供支持。产品通常由印刷电路板组成，板上已装有重点器件以及必要或有用的支持元器件，另外也可能包括其他组件，例如电缆或电源。对于数量特别多或类别独特的器件类别(如 ADC、DAC 和开关模式电源)，评估平台可组合为一个单独的产品系列。

GENERAL DESCRIPTION

The AD9958 consists of two DDS cores that provide indepen dent frequency, phase, and amplitude control on each channel. This flexibility can be used to correct imbalances between signals due to analog processing, such as filtering, amplification, or PCB layout related mismatches. Because both channels share

a common system clock, they are inherently synchronized. Synchronization of multiple devices is supported.

FEATURES

2 synchronized DDS channels @ 500 MSPS

Independent frequency/phase/amplitude control between channels

Matched latencies for frequency/phase/amplitude changes

Excellent channel-to-channel isolation (>72 dB)

Linear frequency/phase/amplitude sweeping capability

Up to 16 levels of frequency/phase/amplitude modulation (pin-selectable)

2 integrated 10-bit digital-to-analog converters (DACs)

Individually programmable DAC full-scale currents

0.12 Hz or better frequency tuning resolution

14-bit phase offset resolution

10-bit output amplitude scaling resolution

Serial I/O port interface (SPI) with 800 Mbps data throughput

Software-/hardware-controlled power-down

Dual supply operation (1.8 V DDS core/3.3 V serial I/O)

Multiple device synchronization

Selectable 4× to 20× REFCLK multiplier (PLL)

Selectable REFCLK crystal oscillator

56-lead LFCSP
