LV7844DW-125.0M-1K
物料型号: - LV7x系列,具体型号根据频率、供电电压和温度范围等参数确定。例如,LV76D和LV78D分别代表两个不同的系列型号。

器件简介: - LV76D/LV78D系列是由Pletronics生产的石英晶体控制的精密方波发生器,具有LVDS输出。它们基于FR4基板,并配有机械金属盖。焊盘兼容许多9x14mm的塑料J引脚封装。

引脚分配: - 1号引脚:不连接(No connect) - 2号引脚:输出使能/禁用(Output Enable/Disable) - 3号引脚:地(Ground, GND) - 4号引脚:输出(Output) - 5号引脚:输出(Output) - 6号引脚:供电电压(Supply Voltage, Vcc)

参数特性: - 供电电压范围:-0.5V至+5.0V - 输出电压范围:-0.5V至Vcc+0.5V - 频率范围:80至250MHz - 频率准确度:根据不同型号,分别为-50/+50ppm、-25/+25ppm和-20/+20ppm - 输出波形:LVDS - 最大输出高电平:1.60V - 最小输出低电平:0.90V - 差分输出电压:±454mV - 输出偏移电压:1.125V至1.375V - 差分输出误差:±50mV - 输出对称性:45%至55%

功能详解: - 该振荡器具有使能/禁用功能,包括低待机功耗模式。 - 使用第三泛音晶体以降低抖动。 - LV77系列使用5x7mm封装。

应用信息: - 推荐在设备下方布置地平面,避免在设备下方布局大的瞬态信号,并远离大的磁场,例如高频开关电源,以获得最佳抖动性能。

封装信息: - 封装尺寸为9.04mm x 8.23mm(S封装)。 - 封装材料包括FR4 PCB基板、焊盘掩蔽、所有过孔在底部覆盖、铜层厚度为670微英寸(17微米)、镍镀层厚度为118微英寸(3微米)和金镀层厚度为0.8微英寸(0.02微米)。
