UB947 EVM with external clk

Hi

 I have a basic question about the UB947 & UB948 EVM communication.

 How can I use the EVMs with external clk on UB947 EVM?

 It is ok using internal clock at the pattern generation by ALP tool. However, it is NG using external clock for clk1 on UB947 EVM board. The LOCK’s led on UB948 EVM board has never turned on.The circuit changed to place U1, R26, R28, R150 andR151. And, J23 and J27 shorted on UB947 EVM for 96MHz following DS90Ux947-Q1EVM User's Guide_snlu140a.

 Should I need any other operation to tarn on the LOCK's LED?

Regards,
Kenshow
