嗨，大家好，
我正在使用VC 707
开发板，我创建了一个10G基础PCS PMA内核，现在我想检查回路。但是在ug885_VC 707（用户手动）中共有5个时钟源页面没有28
1> SYSCLK_N
SYSCLK_P
2> USER_CLOCK_N
USER_CLOCK_P
3> SMA_MGT_REFCLK_N
SMA_MGT_REFCLK_P
4> USER_SMA_CLOCK_N
USER_SMA_CLOCK_P
5> Si5324_OUT_N
Si5324_OUT_P
SFP +连接在收发器组113和内部收发器组113中，有两个时钟源SGMII_CLK和SMA_MGT_REFCLK
现在我尝试每个时钟源，但时钟不工作。
哪个时钟源可用于SFP +和pcs pma核心，我不明白
任何人都可以告诉我，我该怎么办，请帮助我
我的XCF文件是：
set_property PACKAGE_PIN AM4 [get_ports txp] set_property PACKAGE_PIN AM3 [get_ports txn] set_property PACKAGE_PIN AL6 [get_ports rxp] set_property PACKAGE_PIN AL5 [get_ports rxn] set_property PACKAGE_PIN AP33 [get_ports tx_disable] set_property IOSTANDARD LVCMOS18 [get_ports tx_disable]

#set_property PACKAGE_PIN AH7 [get_ports Srefclk_n] #set_property PACKAGE_PIN AN2 [get_ports refclk_p]
谢谢！
