Hi, 

I designed a Cyclone IV EP4CE6E22N board and i used a 65 mhz crystal for clock input. 

But Jtag Cable not found the device. Should I change crystal to 50 mhz one?

No - that won't be the problem. Providing you have powered the device correctly you should be able to detect the device via JTAG. You don't need any clock source. 

 

Cheers,
