C6678的时钟问题



TI 工程师您好,

1、请问C6678EVM上各个时钟分别设置在多少,手册中提到的DSP输入时钟、peripheral system clock都是指哪个时钟?

2、初始化配置时一般配置在多大时钟频率?

3、我现在在做以太网通信,自制电路板,板子资料上显示156.25MHz PASS是指什么?查看GbE手册上的GbE开关子系统运行在350Mhz是所有的都是这样吗?SGMII  SerDes参考时钟是指哪一个时钟呢?是PASS 吗?

4、我看到GE程序中有KeyStone_PASS_PLL_init()这个函数后面的参数应该如何设置?翻了手册实在很迷糊,期待您的回复
