3.3 V Dual-Loop, 50 Mbps to 3.3 Gbps Laser Diode Driver

GENERAL DESCRIPTION Like the ADN2870, the ADN28721 laser diode driver is designed for advanced SFP and SFF modules, using SFF-8472 digital diagnostics. The device features dual-loop control of the average power and extinction ratio, which automatically compensates for variations in laser characte

3.3 V、雙環(huán)路、50 Mbps至3.3 Gbps激光二極管驅(qū)動(dòng)器

與ADN2870相似，ADN2872激光二極管驅(qū)動(dòng)器針對(duì)先進(jìn)的SFP和SFF模塊而設(shè)計(jì)，采用SFF-8472數(shù)字診斷技術(shù)?？梢詫?duì)平均功率和消光比(ER)進(jìn)行雙環(huán)路控制，以自動(dòng)補(bǔ)償激光特性隨著溫度變化和老化而發(fā)生的變動(dòng)。激光器只需要在25°C進(jìn)行校準(zhǔn)，不需要進(jìn)行昂貴且耗時(shí)的溫度校準(zhǔn)。ADN2872支持50 Mbps至3.3 Gbps范圍內(nèi)的單速率或155 Mbps至3.3 Gbps范圍內(nèi)的多速率。該器件采用新型報(bào)警方案，可避免因各種激光產(chǎn)生的系統(tǒng)瞬變所導(dǎo)致的關(guān)斷問題。\n\n 平均功率和ER可以利用微控制器數(shù)模轉(zhuǎn)換器(DAC)或可調(diào)電阻所提供的電壓進(jìn)行設(shè)置。該器件提供偏置和調(diào)制電流監(jiān)控 ?
