大家好,
DS90CR287/DS90CR288A数据表 对 输入时钟的描述如下:
=====================================================================================================================
输入时钟:启用部件时,输入时钟应始终存在。 如果时钟停止,
应断言PWR DOWN引脚以禁用PLL。
=====================================================================================================================
是 接收器还是发射器的输入时钟?
如果是用于接收器,您如何知道 输入时钟 在PWR DOWN模式下处于激活状态?
此致,
Toshi
