LTC®6902 是一款精准、低功率和易于使用的振荡器,其在小型封装中提供了多相输出。振荡器频率由单个外部电阻器 (RSET) 来设定。另外,LTC6902 还提供了一种任选的扩频频率调制 (SSFM) 功能,该功能可利用一个附加的外部电阻器 (RMOD) 来启动和控制。

LTC6902 的主振荡器受控于 RSET 电阻器,并具有一个 100kHz 至 20MHz 的范围。为了适应较宽的输出频率范围,该器件内置了一个可编程分频器 (1、10 或 100 分频)。集成型可编程多相电路可提供 2 相、3 相或 4 相波形。

LTC6902 的 SSFM 功能利用一个伪随机噪声 (PRN) 信号来调制振荡器的频率,以把振荡器的能量散布在一个很宽的频段内。这种能量散布可降低峰值电磁辐射水平并改善电磁兼容性 (EMC) 性能。扩频度可利用一个附加的外部电阻器 (RMOD) 来设置,并通过把 MOD 引脚接地来停用。
