AD9958/PCB開發(fā)板套件編程器的評(píng)估演示板及套件規(guī)格書PDF中文資料

AD9958/PCB屬于開發(fā)板套件編程器的評(píng)估演示板及套件。由亞德諾半導(dǎo)體技術(shù)有限公司制造生產(chǎn)的AD9958/PCB評(píng)估和演示板及套件該系列產(chǎn)品提供了一種方便的方法，在經(jīng)過驗(yàn)證的實(shí)施環(huán)境中評(píng)估某些重點(diǎn)器件的性能或特性。評(píng)估方法通常有完善的文檔說明，并且視乎具體情況由評(píng)估軟件提供支持。產(chǎn)品通常由印刷電路板組成，板上已裝有重點(diǎn)器件以及必要或有用的支持元器件，另外也可能包括其他組件，例如電纜或電源。對(duì)于數(shù)量特別多或類別獨(dú)特的器件類別(如 ADC、DAC 和開關(guān)模式電源)，評(píng)估平臺(tái)可組合為一個(gè)單獨(dú)的產(chǎn)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

APPLICATIONS
