為得到性能優良、符合實際工程的鎖相環頻率合成器，提出了一種以ADI的仿真工具ADIsimPLL為基礎，運用ADS（Advanced Design System 2009）軟件的快速設計方法。采用此方法設計了頻率輸出為930~960 MHz的頻率合成器。結果表明該頻率合成器的鎖定時間、相位噪聲以及相位裕度等指標均達到了設計目標。
Abstract: This document explains how the Cupertino (MAXREFDES5#) subsystem reference design meets the higher resolution, higher voltage,and isolation needs of industrial control and industrial automation applications. Hardware and firmware design files as well as FFTs andhistograms from lab measurements are provided.
Industrial systems demand semiconductors that are precise, flexibleand reliable. Linear Technology offers a broad line of high performanceanalog ICs that simplify system design with rugged devices featuringparameters fully guaranteed over the -40°C to 85°C temperature range.We back this up with knowledgeable applications support, long productlife cycles and superior on-time delivery.
