1. 物料型号 - LV78D系列,3.3V LVDS时钟振荡器,停产于2008年1月,被LV98xxDV和LV93xxDV设备替代。

2. 器件简介 - Pletronics' LV78D系列是一个由石英晶体控制的精密方波发生器,具有LVDS输出。基于FR4材料,配有机械金属外壳。焊盘与许多9x14mm塑料J引线封装兼容。内部在Vcc引线上有旁路电容器,提供胶带和卷带包装。

3. 引脚分配 - 1号引脚:无连接,内部无连接。 - 2号引脚:输出使能/禁用,当该引脚电压小于0.30伏时,输出将被禁止(高阻态)。如果该引脚未连接,振荡器将工作。建议将此引脚连接至VCC,如果振荡器需要始终工作。 - 3号引脚:地(GND)。 - 4号引脚:输出,输出必须被终止,输出之间100欧姆是理想的终结。 - 5号引脚:输出。 - 6号引脚:(VCC)供电电压,建议尽可能靠近连接适当的电源旁路电容器。

4. 参数特性 - 频率范围:80至250MHz。 - 频率精度:"45"精度为-50至+50ppm,"44"精度为-25至+25ppm,"20"精度为-20至+20ppm。 - 输出波形:LVDS。 - 输出高电平:1.60伏,输出低电平:0.90伏。 - 差分输出(Voo):247至454毫伏。 - 输出偏移电压(Vos):1.125至1.375伏。 - 差分输出误差(dVos):50毫伏。 - 输出对称性:45至55%。 - 抖动:300ps至700ps,0.15ps RMS。 - Vcc供电电流:66毫安。 - 使能/禁用内部上拉电阻:50千欧姆至Vcc(等效电阻)。 - V禁用:0.8伏,V启用:2.0伏。 - 输出漏电:-10至+10微安。 - 使能时间:10纳秒,禁用时间:10纳秒。 - 启动时间:5毫秒。

5. 功能详解 - 该设备包含一个低抖动的5x7毫米LCC陶瓷振荡器,使用第三泛音晶体。具有使能/禁用功能,包括低待机功耗模式。

6. 应用信息 - 推荐将1号和2号引脚连接在一起,以允许设计接受两个输入引脚上的使能/禁用(参见LV76D,1号引脚上的E/D)。为获得最佳抖动性能,Pletronics建议:在设备下方有一个地平面,不要在设备下方布局大的瞬态信号(电流和电压),不要靠近大磁场布局,如高频开关电源,不要放置在压电蜂鸣器或机械风扇附近。

7. 封装信息 - 封装尺寸和公差详细描述了固定尺寸和可变尺寸,包括胶带尺寸、最大和最小尺寸等。封装不是密封的(内部的晶体单元是密封的)。侧面故意留空,以便清洁材料可以自由流动,从而最小化清洁过程中污染物的积累。在操作之前,必须确保内部部分完全干燥。
