Pulse Width Modulator

GENERAL DESCRIPTION The AD9561 is a second generation high speed, digitally programmable pulse width modulator (PWM). Output pulse width is proportional to an 8-bit DATA input value. Two additional control inputs determine if the pulse is placed at the beginning, middle or end of the clock period

脈寬調(diào)制器

AD9561是第二代高速、數(shù)字可編程脈寬調(diào)制器（PWM）。輸出脈沖寬度與8位數(shù)據(jù)輸入值成比例。另外兩個(gè)控制輸入確定脈沖是否位于時(shí)鐘周期的開始、中間或結(jié)束處。脈沖寬度和位置可隨每個(gè)時(shí)鐘周期而改變，頻率最高達(dá)60 MHz。\n\n在掃描激光打印引擎應(yīng)用中，脈沖寬度調(diào)制是用于控制灰階和分辨率增強(qiáng)的一種成熟方法。在中低成本掃描電子照相系統(tǒng)應(yīng)用中，調(diào)制脈沖寬度是實(shí)現(xiàn)連續(xù)色調(diào)再現(xiàn)和分辨率增強(qiáng)的經(jīng)濟(jì)有效的方法。\n\nAD9561采用精密模擬電路來控制點(diǎn)尺寸，從而能夠?qū)崿F(xiàn)接近照相品質(zhì)的圖像，無需所有數(shù)字方式所要求的高頻時(shí)鐘信號(hào)。\n\n與其前款產(chǎn)品AD9560相比，AD9561的特性和性能得到了提高。改善的
